Basaloid follicular hamartoma (BFH) is a rare, benign neoplasm of the hair follicle, characterized by multiple brown papules involving the face, scalp, and trunk. It is described by multiple clinical forms, and can present as localized or generalized. Diagnosis is made histologically via biopsy, which is important in order to distinguish BFH from basal cell carcinoma (BCC) or other malignant epithelial neoplasms. Read More

Blaschkitis and lichen striatus are generally distinguished in the literature by the age of onset, lesion distribution, and histopathology. However, there is currently no clear consensus among authors about whether to consider blaschkitis and lichen striatus different clinical entities or a spectrum ofthe same disease. We present a case of adult BLAISE with features of both lichen striatus and blaschkitis, which seems to support the theory that these clinical entities may in fact represent a spectrum of the same pathological process.

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 striatus is an acquired, benign, linear inflammatory dermatosis characterized by a sudden skin eruption along Blaschko's lines that usually is not associated with specific etiologic agents. In most cases, it is a self-limited dermatosis, but may relapse. Topical steroids are its first-line therapy, but this treatment is not always effective. Read More

It usually occurs in young children, sexually active adults, and immunocompromised individuals. The typical clinical picture of this infection is characterized by asymptomatic flesh-colored, single or multiple papules, measuring 2-6 mm in diameter with a central umbilication that occur on the skin and the mucous membranes.

Linear dermatoses are unusual entities whose distribution reflects cutaneous mosaicism, even when they occur in adult life. Adult blaschkitis (AB) and lichen striatus (LS) always follow this peculiar distribution. Although usually referred to as distinct entities, the clinical and histopathological presentation of lichen striatus in adults may be similar to those of adult blaschkitis. Read More

Background: Cholangiocarcinoma (CCA) is one of the most fatal malignant tumors with increasing incidence, mortality, and insensitivity to traditional chemo-radiotherapy and targeted therapy. Chimeric antigen receptor-modified T cell (CART) immunotherapy represents a novel strategy for the management of many malignancies. However, the potential of CART therapy in treating advanced unresectable/metastatic CCA is uncharted so far. 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

Background/objectives: In addition to several infectious and neoplastic cutaneous entities, plasmacytoid dendritic cells (pDCs) have been shown to be involved in the pathogenesis of multiple cutaneous inflammatory and autoimmune disorders, including those characterized histologically by an "interface dermatitis" pattern such as lupus or lichen planus (LP), but their role in lichen striatus (LS), which is also known to have this histologic inflammatory pattern, has never been studied. The objective of the study was to investigate the role of pDCs in LS.

Methods: Fifteen LS patients were found in our database and were immunohistochemically tested for pDC occurrence and activity using anti-blood-derived dendritic cell antigen-2 and anti-myxovirus resistance protein A (MxA) antibodies, respectively. Read More

Diagnostic clues are emphasized to familiarize readers with features that indicate the correct diagnosis.

Lichen striatus (LS) is an uncommon dermatosis of unknown etiology that presents as a continuous or interrupted linear band of pink, tan, red or skin-colored papules in a blaschkoid distribution. The lesions are generally solitary and unilateral, but unusual extensive cases with multiple and bilateral lesions have been also described. Albeit LS is typically an asymptomatic and self-limited dermatosis, it may cause a significant psychological distress in some patients, thus requiring an appropriate therapy. Read More
