Mariya Miteva, Samar Sabiq
Frontal fibrosing alopecia (FFA) is an irreversible scarring alopecia with unknown etiology and no cure. The goal is to establish the diagnosis in the early stage, before developing a hairless band of atrophy involving the frontal, temporal scalp and sideburns. Pathology is rarely needed once the disease is clinically apparent. The classic histologic features include follicular dropout with the absence or atrophy of the sebaceous glands and lichenoid lymphohistiocytic infiltrate with concentric layered fibrosis at the upper follicular level...

Androgenic alopecia, also known as pattern hair loss, is a chronic progressive condition that affects 80% of men and 50% of women throughout a lifetime. But despite its prevalence and extensive study, a coherent pathology model describing androgenic alopecia's precursors, biological step-processes, and physiological responses does not yet exist. While consensus is that androgenic alopecia is genetic and androgen-mediated by dihydrotestosterone, questions remain regarding dihydrotestosterone's exact role in androgenic alopecia onset...

BACKGROUND: Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare type of interstitial pneumonia characterized by fibroelastosis. Patients with IPPFE as well as idiopathic interstitial pneumonia often have autoimmune diseases, which sometimes coincide with hypothyroidism (HypoT). However, there have been no reports on the association between IPPFE and HypoT. The purpose of this study was to evaluate the correlation between IPPFE and HypoT. We also examined the pathological features of the thyroid glands from autopsied cases...

We describe 6 incomplete cases of frontal fibrosing alopecia (FFA). All patients were postmenopausal women. Their average age was 60 years; 2 of the women were Caucasian, and the remaining 4 women were of a mixed ethnicity. The disease duration ranged from 3 to 17 years. The patients' lesions presented as irregular alopecic plaques in the frontal and/or temporal regions, with few signs of perifollicular inflammation, slow progression, and progressive loss of the vellus hair in the frontal area. Loss of the eyebrows, facial hyperpigmentation, and loss of the body hair were observed in 3 patients, 1 patient, and 2 patients, respectively...

Tyrosine kinase inhibitors have revolutionized the chemotherapy arena as targeted therapies for a multitude of malignancies. They are more selective than conventional chemotherapy, and often elicit fewer systemic adverse events, however toxicities still exist. Cutaneous toxicities are common and their management presents a novel challenge to physicians and patients. Ponatinib is a third-generation tyrosine kinase inhibitor increasingly reported to cause cutaneous eruption. A 50-year-old woman with a history of chronic myelogenous leukemia presented with a 4-month history of worsening atrophic and ichthyosiform pink plaques involving the axillae, thighs and abdomen; red patches were also observed on the cheeks and forehead...

INTRODUCTION: Frontal fibrosing alopecia (FFA) is a cicatricial alopecia typically occurring in postmenopausal women. The etiology and pathophysiology of FFA is poorly understood but thought to be immune mediated. This study aims to further explore the extent of fibrosis and the inflammatory microenvironment by characterizing Langerhans cells (LCs), helper T cells, cytotoxic T cells and B cells near hair follicles in FFA. METHODS: Eleven paraffin-embedded tissues from patients with a clinical and histopathologic diagnosis of FFA were selected for immunohistochemical studies using CD3, CD4, CD8, CD1a and CD20...

Scurvy results from a deficiency of vitamin C, a nutrient otherwise known as ascorbic acid. Today, scurvy is rare yet emerges in select patients. The patient reported herein developed scurvy secondary to deliberate avoidance of vitamin C-rich foods. Classic cutaneous manifestations of scurvy include follicular hyperkeratosis and perifollicular hemorrhage encompassing coiled "corkscrew" hairs and hairs bent into "swan-neck" deformities. Ecchymoses, purpura, and petechiae are also characteristically prominent...

CONTEXT: Androgenetic alopecia (AGA) is a frequent disorder characterized by progressive hair miniaturization in a very similar pattern among all affected men. The pathogenesis is related to androgen-inducible overexpression of transforming growth factor β-1 from balding dermal papilla cells, which is involved in epithelial inhibition and perifollicular fibrosis. Recent research shows that hair follicle androgen sensitivity is regulated by Hic-5, an androgen receptor co-activator which may be activated by the mechanical stimulation...

Alopecia and other hair abnormalities occurring in patients with psoriasis were first recognized over four decades ago, yet psoriatic alopecia is not a well-known concept among clinicians. Alopecia may be directly related to the psoriasis itself, and can affect both the scalp and other parts of the body. On the scalp, psoriatic alopecia most commonly affects lesional skin, but may present as a generalized telogen effluvium. In most cases, there is regrowth of hair, but in rare cases it can cause scarring alopecia...

Lichen planopilaris (LPP) is a rare form of cicatricial alopecia that has occasionally been reported in children. Because of the limited number of patients reported, little information is available about demographic characteristics, clinical presentation, or treatment options for these patients. A retrospective chart review of LPP cases in patients under 18 years of age from 1976 to 2013 was performed to further define clinicopathologic features of pediatric LPP. Four pediatric LPP patients ages 13 to 16 years were identified (three male, one female)...

Nevus lipomatosus cutaneous superficialis (NLCS) is a rare cutaneous hamartoma characterized by groups of mature fat cells in the dermis. The authors report a case of a dark-skinnned, 6-year-old, Brazilian girl with 1 lesion in the right upper chest, extending to the neck, since 1 year of age. The dermatological examination consisted of skin-colored and yellowish follicular papules, isolated and grouped into a papillomatous plaque. The biopsy revealed ectopic mature adipose tissue in the dermis, compatible with NLCS, perifollicular well-circumscribed fibroblast and collagen proliferation, and decreased elastic fibers in the papillary and upper reticular dermis...
