Onychomatricoma (OM) is a fibroepithelial tumor of nail matrix that occurs in the digits of both the hands and feet. This was first reported by Baran and Kint. They initially described 3 cases, all of which demonstrated a filamentous tumor of matrix tissue that resulted in a thickened funnel-shaped nail. Although apparently benign, it is subject to(More)
Desmoplastic melanoma (DM) presents diagnostic challenges due to histologic mimics and limited immunohistochemical staining. Although S100 usually stains DM, other melanoma markers (HMB-45 and Melan-A) are often negative. Dermal/subcutaneous mimics of DM [spindle cell/poorly differentiated squamous cell carcinoma, atypical fibroxanthoma (AFX), and sarcoma](More)
The Society for Hematopathology and European Association for Haematopathology workshop, from October 27 to 29, 2011, in Los Angeles, CA, exhibited many exemplary skin biopsy specimens with interesting inflammatory changes mimicking features of cutaneous lymphoma. This article reviews features observed in cutaneous lymphoid hyperplasia, cutaneous drug(More)
OBJECTIVE The aims of this study were to define a novel classification system of tumor perineural invasion (PNI) with respect to tumor/nerve involvement such as intratumoral (IT), peripheral, or extratumoral (ET) and to determine the prognostic significance of each of these histologic subcategories in patients with noncutaneous head and neck squamous cell(More)
Dermal mucinosis is characterized by the deposition of glycosaminoglycans (mucin), either focally or diffusely within the dermis. This may occur as a primary idiopathic disorder or secondary to several dermatoses, most notably lupus erythematous, scleroderma, and dermatomyositis. The authors present an unusual finding of dermal mucinosis in association with(More)
INTRODUCTION Approximately 1 of 4 patients with osteoradionecrosis (ORN) of the mandible develop ongoing disease despite extensive mandible resection to margins determined by the presence of bleeding bone at the time of surgery. OBJECTIVE To determine whether pathologic examination of bony margins in assessing for the presence of necrotic edges is(More)
