    Lichen Planus With Predominate Plasma Cell Infiltrate: Two Case Reports.
    Am J Dermatopathol 2017 Feb;39(2):140-143
    *Department of Dermatology, Lehigh Valley Health Network, Allentown, PA; †School of Osteopathic Medicine, Western University Health Sciences, Pomona, CA; and ‡Advanced Dermatology Associates, LTD, Allentown, PA.
    Lichen planus (LP) is a mucocutaneous inflammatory dermatitis of idiopathic origin that can involve the skin, mucous membranes, hair, and nails. LP has an associated set of characteristic histopathologic findings which include hyperkeratosis, vacuolization of the basal layer, Civatte bodies, wedge-shaped hypergranulosis, band-like lymphocytic infiltrate at the dermal epidermal junction, eosinophilic colloid bodies in the papillary dermis, and pigment incontinence. The infiltrate is usually composed of lymphocytes with few histiocytes, mast cells, and macrophages. Read More

    Exacerbation of Darier Disease under Interferon-α-2a Therapy with Clinical Signs of Lichen Nitidus.
    Case Rep Dermatol 2016 May-Aug;8(2):218-223. Epub 2016 Aug 16.
    Departments of Dermatology, Venereology, Allergology and Immunology, Dessau Medical Center, Dessau, Germany.
    Darier disease/dyskeratosis follicularis is a genodermatosis characterized by brown, oily keratotic papules and plaques in the seborrheic areas of the face and chest. Responsible for the disease are mutations in the ATP2A2 gene, encoding SERCA2, a calcium pump of the sarco-/endoplasmic reticulum. Mechanical trauma, heat, humidity, ultraviolet B radiation, oral corticosteroids and lithium are known trigger factors of the disorder. Read More

    Clinicopathological Study of Non-Infectious Erythaematous Papulosquamous Skin Diseases.
    J Clin Diagn Res 2016 Jun 1;10(6):EC19-22. Epub 2016 Jun 1.
    Professor and Head, Department of Pathology, A J Institute of Medical Sciences , Kuntikana, Mangalore, Karnataka, India .
    Introduction: Papulosquamous diseases are characterized by scaly papules and plaques with similar clinical picture which amounts to confusion and hence, a definitive histopathological diagnosis goes a long way in treatment of such diseases.

    Aim: The aim of the study was to study the histomorphology of non-infectious, erythaematous, papulosquamous lesions of skin with clinicopathological correlation.

    Materials And Methods: Skin biopsies from 150 clinically diagnosed/suspected non-infectious erythaematous, papulosquamous skin diseases were received in the Department of Pathology. Read More

    Langerhans cell histiocytosis mimicking lichen nitidus with bone involvement.
    Australas J Dermatol 2016 Mar 17. Epub 2016 Mar 17.
    Department of Dermatology, Hospital General Universitario Gregorio Marañón, Madrid, Spain.
    We report the case of a 6-month-old Hispanic boy with a 4-month history of widespread pruritic hypopigmented papules mimicking lichen nitidus. The final diagnosis was multisystem non-risk-organ Langerhans cell histiocytosis (LCH), with cutaneous and multiple bone involvement. With this patient and others previously reported in the literature, we suggest an early biopsy of the hypopigmented rash in children. Read More

    Lichen planus and other lichenoid dermatoses: Kids are not just little people.
    Clin Dermatol 2015 Nov-Dec;33(6):631-43. Epub 2015 Sep 12.
    Department of Dermatology, Medical College of Wisconsin, 9200 W. Wisconsin Ave., Wauwatosa, WI 53226.
    Lichenoid dermatoses, a group of inflammatory skin conditions with characteristic clinical and histopathologic findings, range from common to rare. Classic lichen planus typically presents as pruritic, polygonal, violaceous flat-topped papules and plaques; many variants in morphology and location also exist. Other lichenoid dermatoses share similar clinical presentations and histopathologic findings. Read More

    Traumatic neuroma of the penis after circumcision--Case report.
    An Bras Dermatol 2015 May-Jun;90(3):397-9. Epub 2015 Jun 1.
    Complexo Hospitalar Padre Bento de Guarulhos, Guarulhos, SP, Brazil.
    Traumatic neuromas are tumors resulting from hyperplasia of axons and nerve sheath cells after section or injury to the nervous tissue. We present a case of this tumor, confirmed by anatomopathological examination, in a male patient with history of circumcision. Knowledge of this entity is very important in achieving the differential diagnosis with other lesions that affect the genital area such as condyloma acuminata, bowenoid papulosis, lichen nitidus, sebaceous gland hyperplasia, achrochordon and pearly penile papules.

    Perforating lichen nitidus.
    Am J Dermatopathol 2015 May;37(5):406-8
    Division of Dermatopathology, Department of Pathology, University of California, Los Angeles, CA.
    Transepidermal elimination and/or perforation of the epidermis is seen in a variety of conditions but has only rarely been reported in association with lichen nitidus. We describe a case of lichen nitidus with the unique finding of epidermal perforation, a feature that made the usual straightforward diagnosis of lichen nitidus much more difficult. Read More

    Lichen nitidus presenting with nail changes--case report and review of the literature.

    National Skin Centre, Singapore.
    Lichen nitidus of the nail is rare and can precede the onset of skin lesions. Delayed diagnosis is common. We present an unusual case of lichen nitidus-associated nail changes that preceded the onset of skin lesions in a 4-year-old Indian girl. Read More

    Epidermal multinucleated giant cells are not always a histopathologic clue to a herpes virus infection: multinucleated epithelial giant cells in the epidermis of lesional skin biopsies from patients with acantholytic dermatoses can histologically mimic a herpes virus infection.
    Dermatol Pract Concept 2014 Oct 31;4(4):21-7. Epub 2014 Oct 31.
    Division of Dermatology, University of California San Diego, San Diego, California.
    Background: Multinucleated giant cells in the epidermis can either be epithelial or histiocytic. Epithelial multinucleated giant cells are most often associated with herpes virus infections.

    Purpose: To review the histologic differential diagnosis of conditions with epithelial and histiocytic multinucleated giant cells-since multinucleated giant cells in the epidermis are not always pathognomonic of a cutaneous herpes virus infection-and to summarize dermatoses in which herpes virus infection has been observed to coexist.
