Follicular density and ratios in scarring and nonscarring alopecia.
We applied uniform histological criteria and strict statistical measures to compare nonscarring and scarring alopecia. We studied 700 consecutive cases including 355 nonscarring alopecia [136 telogen effluvium, 115 alopecia areata (AA), 95 androgenetic alopecia, and 9 trichotillosis] and 345 scarrin...
Palisaded neutrophilic and granulomatous dermatitis associated with ankylosing spondylitis.
: Palisaded neutrophilic granulomatous dermatitis (PNGD) is a rare neutrophilic dermatosis that shows a broad clinical and histopathological spectrum. The clinical presentation of PNGD varies from asymptomatic papules, to nodules, to annular plaques. The most common clinical presentation is erythema...
The utility of c4d immunohistochemistry on formalin-fixed paraffin-embedded tissue in the distinction of polymorphic eruption of pregnancy f...
We investigated the utility of routine immunohistochemistry (IHC) for anti-C4d in FFPE tissue in the specific differential diagnosis of PEP versus PG in known, DIF-proven cases. We performed C4d IHC on PEP (n = 11), PG (n = 8), DIF-proven BP (n = 12), and other common dermatoses (n = 12) that are ty...
Re-examination of Features to Distinguish Polyarteritis Nodosa From Superficial Thrombophlebitis.
Our findings suggest that no single histopathologic feature is completely reliable and combining the histopathologic features with clinicopathologic correlation is essential for correct vessel identification....
Direct immunofluorescence on hair follicles-present and future perspectives.
: Direct immunofluorescence (DIF) is an important tool for evaluating bullous autoimmune and connective tissue disorders.We report 21 cases of pemphigus vulgaris, bullous pemphigoid and lupus erythematosus that were investigated by performing DIF on scalp hair follicles. The study was done using a s...
Fibrosis-associated single-nucleotide polymorphisms in TGFB1 and CAV1 are not associated with the development of nephrogenic systemic fibros...
We examined whether an intronic single-nucleotide polymorphism (SNP) in caveolin-1 (CAV1 rs4730751) and 2 coding SNPs in transforming growth factor-beta 1 (TGFB1 rs1800471, codon 25; and rs1800470, codon 10) were associated with the NSF phenotype. Forty-one patients with a history of chronic kidney...
Blastic marginal zone lymphoma: a clinical and pathological study of 8 cases and review of the literature.
We describe 8 patients with blastic primary cutaneous marginal zone lymphoma and compare the clinical, pathologic, and molecular findings of these patients with 10 cases previously reported in the literature. : The cases of blastic marginal zone lymphoma could be categorized into cases of de novo bl...
A Case of Pleomorphic Fibroma of the Skin Presenting as Intradermal Nodule.
NK-/T-Cell Lymphoma Resembling Hydroa Vacciniforme With Positive CD4 Marker Expression: A Diagnostic Difficulty.
ABSTRACT:: A 35-year-old Chinese woman presented with a 2.5-year history of facial swelling in the left lower quadrant and a 10-month history of relapsing red papules and vesicles in the perioral area resembling hydroa vacciniforme. Histologically, a tissue biopsy showed a dense infiltration of medi...
Signet-ring cell/histiocytoid carcinoma of the eyelid: a case report and review of the literature.
We report clinical, radiographic, and pathological features of a case of signet-ring cell/histiocytoid carcinoma of the eyelid with review of relevant literature....
