Tinea Versicolor Mimicking Pityriasis Rubra Pilaris
Tinea Versicolor Mimicking Pityriasis Rubra Pilaris Capt Matthew J. Darling, MC, USAF; CPT Matthew C. Lambiase, MC, USA; Capt R. John Young, MC, USAF Tinea versicolor is a common noninvasive cuta- neous fungal disease. We recount a case of tinea versicolor that mimicked type I (classic adult) pityriasis rubra pilaris. A 54-year-old white man reported a 20-year history of a recurrent pruritic eruption that had marginally improved with use of selenium sulfide shampoo and treatment with oral antihistamines. Results of a skin examination revealed erythematous plaques; islands of spared skin; and follicular erythematous keratotic papules on the trunk, shoulders, and upper arms. A lesion was scraped to obtain skin scales for potassium hydroxide staining. Examination of the stained samples revealed the characteristic “spaghetti and meatballs,” confirming the diagnosis. Cutis. 2005;75:265-267. Case Report A 54-year-old white man presented with a 20-year history of a recurrent pruritic eruption that had marginally improved with use of selenium sulfide shampoo and oral antihistamine therapy. Erythem- atous scaly plaques were noted over the trunk and extremities (Figure 1). Islands of spared skin were most notable on the trunk (Figure 2). Follicular, erythematous, keratotic papules were noted on the shoulders and upper arms (Figure 3). Results of Wood lamp examination revealed a yellow-green Figure 1. Erythematous scaly plaques and islands of fluorescence of the plaques. Results of potassium spared skin on the chest. hydroxide (KOH) staining revealed numerous yeast and hyphae. The patient was diagnosed with tinea versicolor and treated with itraconazole 200 mg/d for 2 weeks. -

The aim of this study was to analyze the clinical • Benign tumor features of patients who underwent surgery for an EAC mass confirmed as a benign • Surgical excision lesion. • Recurrence • Infection Methods: This retrospective study involved 53 patients with external auditory tumors who received surgical treatment at Korea University, Guro Hospital. Medical records and evaluations over a 10-year period were examined for clinical characteristics and pathologic diagnoses. Results: The most common pathologic diagnoses were nevus (40%), osteoma (13%), and cholesteatoma (13%). Among the five pathologic subgroups based on the origin organ of the tumor, the most prevalent pathologic subgroup was the skin lesion (47%), followed by the epithelial lesion (26%), and the bony lesion (13%). No significant differences were found in recurrence rate, recurrence duration, sex, or affected side between pathologic diagnoses. -
Bone and Soft Tissue Tumors Have Been Treated Separately

The clinical manifestations of pigmented nevus of the EAC have been reported to include ear fullness, foreign body sensation, hearing impairment, and otalgia, but some cases were asymptomatic and were found incidentally. The treatment of choice for a symptomatic intradermal nevus in the EAC is complete excision. There has been no recurrence reported in the literature . A pedunculated, papillomatous hair-bearing lesion was detected in the external auditory canal of the patient who was on follow-up for pruritus. Clinical and pathologic features of an intradermal nevus of the external auditory canal are presented, and the literature reviewed. Submitted : 14 October 2008 Revised : 01 July 2009 Accepted : 09 July 2009 Intradermal nevus is the most common skin tumor in left external auditory canal. Otomicroscopic humans; however, its occurrence in the external examination revealed a pedunculated, papillomatous auditory canal (EAC) is uncommon [1-4]. Intradermal hair-bearing lesion in the postero-inferior cartilaginous nevus is considered to be a form of benign cutaneous portion of the external auditory canal (Figure 1). -
Critical Evaluation of the So-Called “Junction Nevus”

WILLIAM BECKER, MS., M.D. The serious study of pigmented nevi was undertaken by many workers in the closing years of the 19th Century. All recognized that the microscopic picture of nevi differed from anything seen in other organs. The presence of nevus cells in both the epidermis and dermis led to concepts of origin at one or the other site, or at both sites. Dermal Origin: Demieville (1) believed that the nevus cells arose from adven- titial and endothelial cells of blood vessels. Bauer (2) and vonRecklinghausen (3) thought that the origin was from endothelium of lymph vessels rather than of blood vessels. Epidermal Origin: According to Abesser (4), Duranti, in 1871, was the first to suggest an epidermal origin of nevus cells. Kromayer (5) stated that the endo- thelium-like cells originate in the basal portion of the epidermis as "Bläschen- zellen", migrate to the dermis and develop connective tissue and elastic fibers, a change which he called "desmoplasia". Abesser (4) agreed that the cells origi- ated in the epithelium and lost their intercellular bridges, but migrated into the dermis as epithelium-like cells, and remained such. Unna (6) advanced the concept that the epithelial cells changed by losing their intercellular bridges and multiplied in groups, a process which he called "Ab- sonderung", then migrated as groups to the dermis, which he called "Abtrop- fung", thus forming pigmented nevi. -
A Case of Intradermal Melanocytic Nevus with Ossification (Nevus of Nanta)
197 A Case of Intradermal Melanocytic Nevus with Ossification (Nevus of Nanta) Young Bok Lee, M.D., Kyung Ho Lee, M.D., Chul Jong Park, M.D. Department of Dermatology, College of Medicine, The Catholic University of Korea, Seoul, Korea A 49-year-old woman presented with a 30-year history of asymptomatic plaque on her right temple. The histological examination revealed nests of nevus cells throughout the entire dermis. Bony spicules were seen just beneath the nevus cell nests in the lower dermis. Cutaneous ossification is an unusual event. Herein, we present a case of intradermal melanocytic nevus with unusual ossification (nevus of Nanta).

S. Medical College and King Edward Memorial Hospital, Mumbai, India Abstract Follicular mucinosis occurring along with angiolymphoid hyperplasia with eosinophils (ALHE) has been described in a 49-year-old male. The patient presented with pruritic hyperpigmented papules and nodules on the vertex and right parietal scalp. There was no any other complaint. Histopathological examination from one of the papule showed prominent blood vessels in the dermis lined by plump histiocytoid endothelial cells that were surrounded by a dense lymphoid infiltrate with numerous eosinophils; these findings are typical of angiolymphoid hyperplasia with eosinophilia. Features of follicular mucinosis were observed in the same section with 3 hyperplastic follicular infundibula containing pools of mucin in the infundibular epithelium. The concurrent occurrence of these 2 distinct histopathological patterns in the same biopsy specimen has been reported rarely. Key Words: Angiolymphoid hyperplasia, eosinophilia, follicular mucinosis, scalp What was known? perivascular area and other parts of the dermis. -

Received August 11, 2006; accepted August 29, 2006 ABSTRACT Cutaneous chronic graft versus host disease has traditionally been classified into lichenoid and scleroderma- like forms. However, the initial presentation is sometimes subtle and a variety of less common cutaneous manifestation may be prevalent. This clinical review focuses on the lesional morphology of chronic graft versus host disease, and presents a classification system that may prove useful in early diagnosis. In addition, this approach may help to facilitate the correlation of different morphologic entities with outcome and response to therapy. © 2006 American Society for Blood and Marrow Transplantation KEY WORDS Stem cell transplant ● GVHD ● Dermatology INTRODUCTION scribe and summarize the diversity of cutaneous manifestations of cGVHD in Table 1.

2016 Essentials of Dermatopathology Slide Library Handout Book April 8-10, 2016 JW Marriott Houston Downtown Houston, TX USA CASE #01 -- SLIDE #01 Diagnosis: Nodular fasciitis Case Summary: 12 year old male with a rapidly growing temple mass. Present for 4 weeks. Nodular fasciitis is a self-limited pseudosarcomatous proliferation that may cause clinical alarm due to its rapid growth. It is most common in young adults but occurs across a wide age range. This lesion is typically 3-5 cm and composed of bland fibroblasts and myofibroblasts without significant cytologic atypia arranged in a loose storiform pattern with areas of extravasated red blood cells. Mitoses may be numerous, but atypical mitotic figures are absent. Nodular fasciitis is a benign process, and recurrence is very rare (1%). Recent work has shown that the MYH9-USP6 gene fusion is present in approximately 90% of cases, and molecular techniques to show USP6 gene rearrangement may be a helpful ancillary tool in difficult cases or on small biopsy samples.
