The presence of acquired generalized keratotic follicular papules and comedones developing in adulthood constitute an uncommon clinical situation. Although this clinical presentation has been described in several noninflammatory, inflammatory, and neoplastic skin disorders, its association with an exclusive perifollicular epitheliod or granulomatous inflammatory reaction represents an exceedingly rare phenomenon. We report a case of a 57-year-old male patient presenting clinically numerous acquired disseminated follicular papules and comedones, showing isolated perifollicular sarcoid-like granulomatous inflammatory infiltrates at the histological examination.

Lichen nitidus typically presents as shiny pin-head sized papules on the trunk and extremities, often affecting children and young adults. In this prototypical form, it rarely presents a diagnostic challenge being characterized by distinctive clinical and histopathologic findings. We describe a rare variant of lichen nitidus, which we term "hyperkeratotic and hypertrophic lichen nitidus. Read More

Lichen nitidus is a rare, chronic dermatosis which occurs more often in children than in adults. It presents with tiny, monomorphous, lichenoid, mostly asymptomatic papules in regional or disseminated distribution which show a pathognomonic histological pattern. The pathogenesis is unclear; however, immunologic phenomena and genetic factors are under discussion. Read More

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

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 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

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

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

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 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.

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

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.

The disorder is most often localized but, rarely, can become extensive or generalized. The occurrence of lichen nitidus during infancy is extremely rare. Read More
