    Department of Oral Pathology and Microbiology, KLE Viswanath Katti Institute of Dental Sciences, KLE University, Belagavi, India.
    Cutaneous lymphoid hyperplasia (CLH) is a cutaneous pseudolymphoma with a worldwide distribution, equally affecting all races and ethnic groups. Due to its vast array of characteristics, it is most often missed in the differential diagnosis of firm to soft lumps on the head and neck. A systematic approach to the workup and diagnosis along with treatment of such lesions is discussed in this article. Read More

    [Differential diagnosis of basal cell carcinoma of the face: Dermatologist advice may avoid surgery].
    Rev Stomatol Chir Maxillofac Chir Orale 2016 Nov 14;117(5):335-339. Epub 2016 Jul 14.
    Aix Marseille université, 13916 Marseille, France; Service de dermatologie, hôpital Nord, AP-HM, 13915 Marseille cedex 20, France.
    Introduction: Basal cell carcinoma (BCC) is the most common skin cancer in France. It is commonly diagnosed in front of a papule or nodule of the face. The surgeon should be able to question the diagnosis of BCC when nodular lesions are untypical, keeping in mind that some differential diagnoses require only medical treatment. Read More

    Cutaneous metastasis of inflammatory breast carcinoma mimicking an erythema annulare centrifugum: a sign of locally recurrent cancer.

    Tinea on a Tattoo.
    Acta Dermatovenerol Croat 2016 Aug;24(3):223-4
    Marius Irimie, MD, 40, Zizinului Street, Bl. 31, Sc. C, Ap. 2, 500414, Brasov, Romania;
    In the last twenty years, the prevalence of individuals with tattoos in the general population has increased in Europe (1) as well as in Australia (2) and the United States of America (3). A series of complications such as acute inflammatory reactions, allergic contact dermatitis (4,5), photoinduced, lichenoid, and granulomatous reactions (6, 7), pseudolymphoma (8), pseudoepitheliomatous hyperplasia (9), skin infections (6), and skin cancers (10) may occur on tattoos. Infectious complications on tattoos include bacterial infections (pyoderma, leprosy, syphilis, cutaneous tuberculosis, mycobacteriosis) (11-14), viral infections (molluscum contagiosum, warts, herpes simplex, hepatitis B and C) (15-17), and fungal infections (sporotrichosis, dermatophytosis) (18,19).

    Papular angiolymphoid hyperplasia and lymphoplasmacytic plaque: a clinical and histological spectrum.
    Dermatol Online J 2016 Apr 18;22(4). Epub 2016 Apr 18.
    Singapore General Hospital.
    Acral pseudolymphomatous angiokeratoma of children (APACHE) is a rare form of cutaneous pseudolymphoma characterized byangiomatous papules with a predilection for the acral regions of children. Classically, a dense dermal lymphocytic infiltrate composed of both T and B cells is seen in histological specimens, together with prominent vessels lined by plump endothelial cells. Increasing evidence suggests that this condition is neither necessarily acral, pseudolymphomatous, nor angiokeratomatous. Read More

    Pseudolymphoma versus lymphoma: An important diagnostic decision.
    J Oral Maxillofac Pathol 2016 May-Aug;20(2):328
    Department of Conservative Dentistry and Endodontics, Farooqia Dental College, Mysuru, Karnataka, India.
    Small innocuous growths on the face usually do not pose difficulty in diagnosis on histopathology. However, some benign inflammatory lesions might mimic malignancy and hence need further investigations for final diagnosis. The distinction between a benign/inflammatory/malignant lesion needs no emphasis as the treatment plan, prognosis and the patient's well-being depends on it. Read More

    Approach to Cutaneous Lymphoid Infiltrates: When to Consider Lymphoma?
    Indian J Dermatol 2016 Jul-Aug;61(4):351-74
    Department of Dermatology and Pathology, University of California, San Francisco, United States of America.
    Cutaneous lymphoid infiltrates (CLIs) are common in routine dermatopathology. However, differentiating a reactive CLI from a malignant lymphocytic infiltrate is often a significant challenge since many inflammatory dermatoses can clinically and/or histopathologically mimic cutaneous lymphomas, coined pseudolymphomas. We conducted a literature review from 1966 to July 1, 2015, at PubMed. Read More

    Differential NFATc1 Expression in Primary Cutaneous CD4+ Small/Medium-Sized Pleomorphic T-Cell Lymphoma and Other Forms of Cutaneous T-Cell Lymphoma and Pseudolymphoma.
    Am J Dermatopathol 2017 Feb;39(2):95-103
    Department of Pathology and Laboratory Medicine, Weill Cornell Medicine, New York, NY.
    Background: Primary cutaneous CD4 small/medium-sized pleomorphic T-cell lymphoma (PCSTCL) has recently emerged as a distinct clinicopathological entity. Because of a considerable degree of overlap with pseudolymphoma, the diagnosis is often challenging. Preliminary studies suggest that nuclear upregulation of calcineurin/nuclear factor of activated T cells (NFAT) may play a role in lymphomagenesis. Read More

    Cutaneous pseudolymphomas are benign lymphoproliferative processes mimicking lymphomas clinically and histologically. One of the precipitating factors for pseudolymphoma is drugs like anticonvulsants, antidepressants and angiotensin-converting enzyme inhibitors. According to existing literature phenytoin-induced cutaneous pseudolymphomas are usually T-cell predominant. Read More

    Linear acral pseudolymphomatous angiokeratoma of children with associated nail dystrophy.
    Dermatol Online J 2015 Jul 15;21(7). Epub 2015 Jul 15.
    Baylor Scott & White Health, Texas A&M Health Science Center.
    Acral pseudolymphomatous angiokeratoma of children (APACHE) is a rare entity that typically occurs on the extremities of young females. Although linear arrangement of cutaneous lesions has been rarely reported, accompanying nail dystrophy has not been linked with this condition to our knowledge. We describe a case of linearly-oriented infiltrative papules and nodules on the index finger of a young female with associated onychodystrophy. Read More

    The importance of histopathology findings in lymphomatoid papulosis.
    Rom J Morphol Embryol 2014 ;55(4):1527-30
    Discipline of Dermatology, Faculty of Medicine, "Grigore T. Popa" University of Medicine and Pharmacy, Clinic of Dermato-venereology, "St. Spiridon" Emergency Hospital, Iassy, Romania;
    Lymphomatoid papulosis, part of the controversial group of cutaneous lymphoproliferative pseudolymphoma disorders, raises important clinical and histopathological problems. It is a chronic, recurrent, clinically characterized by popular necrotic lesions and papulo-pustular nodules, sometimes self-limiting and characterized by histopathological changes suggestive of cutaneous lymphoma (CD30-positive). Since its introduction, in 1968, the term "lymphomatoid papulosis" was subject to dispute in terms of classification in malignancies, premalignant or benign skin disease. Read More

    A variant of palpable migratory arciform erythema.
    J Drugs Dermatol 2014 Oct;13(10):1288-9
    Palpable migratory arciform erythema is a T-cell pseudolymphoma with no well-established treatment. The disease is rarely reported in the literature, perhaps because it is difficult to diagnose. We present a case of a variant of PMAE in a 30-year-old healthy man with no history of medication use and erythematous to violaceous annular and arciform plaques on his face, scalp and trunk.

    [Cutaneous lymphomas: new entities and rare variants].
    Pathologe 2015 Feb;36(1):62-9
    Kempf und Pfaltz, Histologische Diagnostik, Seminarstr. 1, 8042, Zürich, Schweiz,
    Primary cutaneous lymphomas are the second most common group of extranodal non-Hodgkin lymphomas. Recently several new variants and entities have been described but have not yet become part of the World Health Organization (WHO) classification. These forms include the granulomatous form of mycosis fungoides, which is associated with a poorer prognosis, as well as indolent CD8+ lymphoproliferations on the head and at acral localizations.

    Borrelial lymphocytoma cutis: a diagnostic dilemma.
    Indian J Dermatol 2014 Nov;59(6):595-7
    Consultant Pathologist, OncQuest Laboratories, 3 Factory Road, New Delhi, India.
    Lymphocytoma cutis (LC) is one of the most common types of cutaneous B cell pseudolymphoma. Borrelial LC occurs most commonly in areas endemic for Ixodes ricinus tick in Europe, and it is rare in North America. The disease is rarely seen in India and may cause diagnostic difficulties for dermatologist residing in parts of the world that are not endemic for Lyme disease. Read More

    Stenotrophomonas maltophilia with histopathological features mimicking cutaneous gamma/delta T-cell lymphoma.
    Int J Infect Dis 2015 Jan 13;30:7-9. Epub 2014 Nov 13.
    Department of Dermatology, The University of Texas Medical School at Houston and MD Anderson Cancer Center, 1400 Pressler Street Unit 1452, Houston, TX 77030, USA.
    We report a case of cutaneous Stenotrophomonas maltophilia infection which presented with clinical and histopathological findings that mimicked a gamma/delta (γδ) T-cell lymphoma. In this case, tissue culture of the biopsy specimen was key to determining the diagnosis and allowing appropriate treatment with oral trimethoprim-sulfamethoxazole and topical silvadene. A prompt complete resolution of lesions was observed following antibiotic treatment, with no recurrence of disease over the last 5 years, supporting an infectious rather than malignant etiology.

    T-cell-predominant lymphoid hyperplasia in a tattoo.
    An Bras Dermatol 2014 Nov-Dec;89(6):1019-21
    aff05.
    Cutaneous lymphoid hyperplasia (CLH) can be idiopathic or secondary to external stimuli, and is considered rare in tattoos. The infiltrate can be predominantly of B or T-cells, the latter being seldom reported in tattoos. We present a case of a predominantly T CLH, secondary to the black pigment of tattooing in a 35-year-old patient, with a dense infiltrate of small, medium and scarce large T-cells. Read More

    PD-1, S-100 and CD1a expression in pseudolymphomatous folliculitis, primary cutaneous marginal zone B-cell lymphoma (MALT lymphoma) and cutaneous lymphoid hyperplasia.
    J Cutan Pathol 2015 Jan 11;42(1):6-15. Epub 2014 Dec 11.
    Dermatopathology Unit, Massachusetts General Hospital, Boston, MA, USA.
    Background: Pseudolymphomatous folliculitis is a lymphoid proliferation that clinically and histopathologically mimics primary cutaneous extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). In this study, we assessed the diagnostic value of three immunohistochemical markers, programmed death-1 (PD-1), CD1a and S100.

    Methods: We evaluated 25 cases of cutaneous lymphoid proliferations with established diagnoses, including 9 patients with pseudolymphomatous folliculitis, 11 with MALT lymphoma, and 5 with cutaneous lymphoid hyperplasia (CLH). Read More

    T cell lymphomatoid contact dermatitis: a challenging case and review of the literature.
    Contact Dermatitis 2015 Feb 24;72(2):65-74. Epub 2014 Oct 24.
    Section of Dermatology, Department of Surgery, Dartmouth-Hitchcock Medical Center, One Medical Center Drive, Lebanon, NH 03766, USA.
    Lymphomatoid contact dermatitis is a pseudolymphoma with clinical and histological features of allergic contact dermatitis and cutaneous T cell lymphoma. Incorrect diagnosis may lead to unnecessary testing, unnecessary treatment, or patient harm. The objective of this study is to present a case to demonstrate the diagnostic challenge and overlap between allergic contact dermatitis and cutaneous T cell lymphoma in a patient with lymphomatoid contact dermatitis caused by methylchoroisothiazolinone/methylisothiazolinone and paraben mix, and to review the existing literature in order to summarize the demographics, clinical features, allergens and treatments reported for lymphomatoid contact dermatitis.

    Selected inflammatory imitators of mycosis fungoides: histologic features and utility of ancillary studies.
    Arch Pathol Lab Med 2014 Oct;138(10):1319-27
    From the Departments of Pathology (Drs Arps, Chen, Fullen, and Hristov) and Dermatology (Drs Fullen and Hristov), University of Michigan, Ann Arbor.
    Mycosis fungoides is the most common primary cutaneous lymphoma; however, it remains a significant diagnostic challenge, in part because of the overlap with several inflammatory dermatoses. Despite advances in immunohistochemistry and molecular diagnostics, false-positive, false-negative, and indeterminate diagnoses are not uncommon. In most cases, the overall balance of morphologic, immunophenotypic, and genetic features must be considered carefully because there are few sensitive and specific clues to the diagnosis. Read More

    Controversies and considerations in the diagnosis of primary cutaneous CD4⁺ small/medium T-cell lymphoma.
    Arch Pathol Lab Med 2014 Oct;138(10):1307-18
    From the Departments of Pathology (Drs Lan, Brown, and Hristov) and Dermatology (Drs Lan and Hristov), University of Michigan Health System, Ann Arbor.
    Context: Primary cutaneous CD4⁺ small/medium T-cell lymphoma is a provisional and controversial entity with a broad differential diagnosis. Despite being an uncommon lymphoma, it is a frequent diagnostic consideration in cutaneous biopsies with a dense lymphoid infiltrate because it shows overlapping features with reactive lymphoid hyperplasia (pseudolymphoma) and a variety of other primary cutaneous and systemic lymphomas. However, proper classification of this process is important for determining patient prognosis and treatment options. Read More

    Drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms with histologic features mimicking cutaneous pseudolymphoma.

    Department of Dermatology, PSG Institute of Medical Sciences and Research, Coimbatore, Tamil Nadu, India.
    Cutaneous pseudolymphomas refer to a group of benign reactive T or B cell lymphoproliferative processes that simulate cutaneous lymphomas. T cell rich angiomatoid polypoid pseudo lymphoma (TRAPP) of the skin is a unique form of T cell rich cutaneous pseudolymphoma. A 13-year-girl presented with an asymptomatic skin colored papule on the right elbow, the biopsy of which revealed features consistent with TRAPP. Read More

    IgG4-related skin disease.
    Br J Dermatol 2014 Nov 20;171(5):959-67. Epub 2014 Oct 20.
    Department of Dermatology, Hamamatsu University School of Medicine, 1-20-1 Handayama, Higashi-ku, Hamamatsu, 431-3192, Japan.
    IgG4-related disease (IgG4-RD) is a recently established clinical entity characterized by high levels of circulating IgG4, and tissue infiltration of IgG4(+) plasma cells. IgG4-RD exhibits a distinctive fibroinflammatory change involving multiple organs, such as the pancreas and salivary and lacrimal glands. The skin lesions of IgG4-RD have been poorly characterized and may stem not only from direct infiltration of plasma cells but also from IgG4-mediated inflammation. Read More

    G Ital Dermatol Venereol 2014 Apr;149(2):227-35
    Unit of Dermatology "A. Perrino" Hospital , Brindisi, Italy.
    Skin is the main sufferer of the adverse drug reactions (ADRs), being involved in 30% of all ADRs cases. However, ADRs are generally underestimated because of the difficulty to correlate the event to a particular drug. A careful anamnestic history is crucial to establish the causal link between an ADR and the specific drug. Read More

    Asynchronous presentation of follicle center lymphoma and reactive lymphoid hyperplasia of the ocular adnexa.
    Am J Dermatopathol 2014 Apr;36(4):e87-92
    *Department of Dermatology and Cutaneous Biology, Jefferson Medical College of Thomas Jefferson University, Philadelphia, PA; †Center for Excellence in Eye Care, Miami, FL; and ‡Jefferson Medical College, Philadelphia, PA.
    Although ocular lymphoproliferative diseases may be rarely encountered by dermatopathologists, the frequency may increase particularly as more and more subspecialties rely on dermatopathology services. Emerging data suggest that there are some similarities between ocular and cutaneous lymphoproliferative diseases with respect to their clinical behavior, prognosis, and cytogenetics. In this case report, a patient with ocular follicle center lymphoma who subsequently developed ocular reactive lymphoid hyperplasia is presented with an accompanying review of the literature on the subjects.
