[Pathology of the nipple-areola complex : Part II. Tumors, tumor-like lesions, and supernumerary breast lesions].

Pathologe 2020 May 26. Epub 2020 May 26.

Pathologisches Institut, Universitätsklinikum Heidelberg, Im Neuenheimer Feld 224, 69120, Heidelberg, Deutschland.

The nipple-areola complex is the origin of various morphologically distinct tumors and tumor-like lesions, which can be delineated from the special structures of the nipple, in particular the intramammary ducts, skin-appendages, and the intramammary stroma. Benign tumors are most frequent and this includes epithelial tumors such as mammary adenoma and syringomatous tumor of the nipple. Less commonly observed are benign mesenchymal tumors such as leiomyoma of the nipple, or tumor-like lesions like pseudo-lymphoma. Read More

and Can Form Mixed Biofilms in Infected Human Skin Tissues.

Eur J Microbiol Immunol (Bp) 2019 Jun 11;9(2):46-55. Epub 2019 Apr 11.

Department of Dermatology and Venereology, Medical University Innsbruck, Innsbruck, Austria.

Our research group has recently shown that , the Lyme disease bacterium, is capable of forming biofilms in Borrelia-infected human skin lesions called lymphocytoma (BL). Biofilm structures often contain multiple organisms in a symbiotic relationship, with the goal of providing shelter from environmental stressors such as antimicrobial agents. Because multiple co-infections are common in Lyme disease, the main questions of this study were whether BL tissues contained other pathogenic species and/or whether there is any co-existence with biofilms.

1st Department of Dermatology "Andreas Syggros" Hospital, Medical School, National and Kapodistrian University of Athens, Athens, Greece.

Although anti-TNFα agents have revolutionized the treatment of many inflammatory diseases, various concerns have been reported regarding the risks of cancer development, as well as acceleration of the progression of subclinical, preexisting malignancies. In this case series, we investigated the provocative effect of anti-TNFα drugs in the development of cutaneous mycosis fungoides (MF)-like lymphoproliferative reactions. We describe five patients aged between 25-63 diagnosed with autoimmune disorders (psoriatic arthritis - one patient, Crohn's disease - one patient and ankylosing spondylitis - three patients) who received anti-TNFα agents before the development of a cutaneous lymphoproliferative reaction.

Primary cutaneous lymphomas are a heterogeneous group that includes 2 main groups of primary T- and B-cell lymphomas, which can involve the skin with distinct variability in clinical presentation, histopathology, immunophenotypes, molecular signature, and prognosis. The authors describe the most frequent clinical forms of cutaneous lymphomas and their dermoscopic features. Even if the diagnosis of these entities is still based on a cellular level and the literature on dermoscopy in cutaneous lymphomas is limited and, for several entities it is based only on single case reports/case series, we think that know how they appear also in dermoscopy can be useful for helping in the clinical diagnosis.

Approach to dermal-based lymphoid infiltrates and proliferations.

Semin Cutan Med Surg 2018 Mar;37(1):61-74

Department of Pathology, The American British Cowdray Medical Center, Mexico City, Mexico.

The histopathological diagnosis of dermal-based lymphoid infiltrates and proliferations is often challenging due to the vast list of biologically diverse entities that archetypally or occasionally center in the mid-dermis, especially because significant overlap exists in their clinical, histopathologic, and immunophenotypic features. The differential diagnosis includes reactive infiltrates in common and rare inflammatory dermatoses, benign conditions that may mimic lymphoid neoplasms (pseudolymphomas), and true clonal proliferations arising either primarily in the skin or rarely in extracutaneous tissues with secondary cutaneous dissemination. While numerous histopathological and immunophenotypic features have been reported to support a definitive diagnosis, no single ancillary test is sufficient for their distinction. Read More

Panel Sequencing Shows Recurrent Genetic FAS Alterations in Primary Cutaneous Marginal Zone Lymphoma.

J Invest Dermatol 2018 07 23;138(7):1573-1581. Epub 2018 Feb 23.

Comprehensive Cancer Center Mainfranken, University of Würzburg, Würzburg, Germany; Department of Dermatology, Venereology and Allergology and Skin Cancer Center, University Hospital Würzburg, Würzburg, Germany.

Primary cutaneous marginal zone lymphoma (PCMZL) represents an indolent subtype of non-Hodgkin lymphoma that is clinically characterized by slowly growing skin tumors with a very low propensity for systemic dissemination. The underlying genetic basis of PCMZL has not been comprehensively elucidated. To gain deeper insight into the molecular pathogenesis of PCMZL, we performed hybridization-based panel sequencing of 38 patients with well-characterized PCMZL. Read More

Cutaneous intravascular CD30+ T-cell pseudolymphoma occurring in a regressing keratoacanthoma.

J Cutan Pathol 2018 Apr 18;45(4):296-298. Epub 2018 Feb 18.

Associates in Dermatology, MD PL, Fort Myers, Florida.

Cutaneous intravascular CD30+ pseudolymphoma is an uncommon incidental finding that may mimic intravascular or angiotropic lymphoma. We describe a 78-year-old female with a traumatized regressing keratoacanthoma on her left cheek. A shave biopsy revealed intravascular staining of atypical lymphocytes positive for CD45, CD3 and CD30. Read More

Drug induced pseudolymphoma.

Semin Diagn Pathol 2018 Jul 1;35(4):247-259. Epub 2018 Feb 1.

Regional Medical Laboratory, 4142 South Mingo Road, Tulsa, OK 74146-3632, United States.

Atypical lymphocytic infiltrates of the skin comprise a broad spectrum of entities ranging from benign infiltrates to those that are malignant. Many of these infiltrates are in fact reactive lymphomatoid ones related to drug therapy falling under the general category of drug associated pseudolymphoma. Within this nosologic umbrella are nodular and diffuse infiltrates resembling low grade T and B cell lymphoma consistent with lymphocytoma cutis, drug associated reversible T cell dyscrasias which draw a strong morphologic and phenotypic parallel with mycosis fungoides and the various pre-lymphomatous T cell dyscrasias, and angiocentric CD30 positive infiltrates mirroring lymphomatoid papulosis.

Septolobular panniculitis in disseminated Lyme borreliosis.

J Cutan Pathol 2018 Apr 9;45(4):274-277. Epub 2018 Feb 9.

Departments of Dermatology and Pathology, University of Iowa Hospitals and Clinics, Iowa City, Iowa.

Lyme disease classically evolves through clinical manifestations according to the stage of illness. Because many of the systemic symptoms are non-specific, and because serology may yield false negative results, cutaneous findings merit even greater importance to diagnosis. The prototypical skin lesion, erythema migrans (EM), occurs early and is the only independent diagnostic clinical feature according to the guidelines of the Infectious Diseases Society of America.

[The key role of the pathologist in the diagnosis of syphilis: A case report].

Ann Pathol 2018 Feb 23;38(1):64-67. Epub 2017 Dec 23.

Syphilis is a resurging sexually transmitted infection linked to Treponema Pallidum. Syphilitic lymphadenitis can be present during the 3 stages of the disease. Its histological diagnosis remains challenging for the pathologist given its possible misleading aspect and its ability to mimic as well as reactional as tumoral conditions. Read More

Lymphocytoma cutis on the inguinal region: report of a rare case of benign lymphoproliferative disorder.

An Bras Dermatol 2017 ;92(5 Suppl 1):98-100

Department of Medicine of the Faculdade Integral Diferencial (Facid-DeVry) - Teresina (PI), Brazil.

Lymphocytoma cutis, or benign reactive lymphoid hyperplasia, is an inflammatory skin lesion that mimics clinically and histologically malignant lymphoma. Most cases are idiopathic, but they may also be triggered by multiple factors, such as insect bites, tattoos, injections and herpes zoster. Clinically, the lesions are erythematous, soft papules, plaques or nodules, usually located on the upper limbs and face. Read More

Areolar lymphocytoma in a child: A rare cutaneous presentation of borreliosis.

Pediatr Dermatol 2018 Jan 4;35(1):e90-e91. Epub 2017 Dec 4.

Division of Dermatology, Department of Pediatrics, School of Medicine, University of Washington and Seattle Children's Hospital, Seattle, WA, USA.

Lyme disease is a common tick-borne infection caused by Borrelia burgdorferi in the United States, where infection is most prevalent in the northeastern and mid-Atlantic states. Although classically associated with erythema migrans, Lyme disease caused by Borrelia species found in Europe may also present with other cutaneous findings. Here we report the case of a girl who was clinically diagnosed with Lyme disease based on her history of recent travel and the appearance of an areolar lymphocytoma; this was confirmed by testing.

Red tattoo-related mycosis fungoides-like CD8+ pseudolymphoma.

J Cutan Pathol 2018 Mar 27;45(3):226-228. Epub 2017 Dec 27.

Department of Dermatology, Mayo Clinic, Rochester, Minnesota.

Cutaneous reactions to red tattoo pigment rarely manifest as pseudolymphomatous reactions. We describe an exceedingly rare case of red tattoo-related T-cell predominant pseudolymphoma microscopically mimicking mycosis fungoides. Careful clinicopathological correlation was required to obtain the correct diagnosis and aid in an effective treatment course. Read More
