Original Research Article Skin Adnexal Tumors- An Institutional Experience 1 2* 3 4 5 6 Rekha M Haravi , Roopa K N , Priya Patil , Rujuta Datar , Meena N Jadhav , Shreekant K Kittur 1,5Associate Professor, 2Post Graduate Student, 3,4Assistant Professor, 6Professor & HOD, Department of Pathology, Belgaum Institute of Medical Sciences Dr B R Ambedkar Road, Belagavi, Karnataka – 590001, INDIA. Email: [email protected] Abstract Background: Skin adnexal tumors are a wide spectrum of benign and malignant tumors that differentiate towards one or more adnexal structures found in normal skin. The adnexal structures of skin are the hair follicles, sebaceous glands, eccrine and apocrine sweat glands. These skin adnexal tumors are often difficult to diagnose clinically. This retrospective study was undertaken to know the various histomorphological patterns of skin adnexal tumors at our institution and to determine the incidence among the genders and age groups along with the site distribution. Materials and methods: A total of 40 specimens received and diagnosed as skin adnexal tumors in the department of Pathology at Belgaum Institute of Medical Sciences, Belagavi for a period of 6 years from January 2014 to December 2019 were taken for the study. Histopathological slides prepared from tissue blocks retrieved from departmental archives were reviewed and classified according to the WHO classification 2017. Results: Out of the total 40 samples, benign tumors were 36 (90%) and malignant were 4 (10%). Largest group was the benign tumors of apocrine and eccrine differentiation (47.5%) followed by benign tumors of hair follicle differentiation (40%). Malignant tumors of sebaceous differentiation were 5%, malignant tumors of eccrine and apocrine differentiation were 2.5% and malignant hair follicle differentiation tumors were 2.5% of the total. -

EYELID & CONJUNCTIVAL TUMORS EYELID & CONJUNCTIVAL TUMORS 5 6 EYELID & CONJUNCTIVAL TUMORS Foreword Dr. Serge Morax I am honored to introduce this Photographic Atlas of palpebral and conjunctival tumors,which is the culmination of the close collaboration between Drs. Olivier Galatoire and Mathieu Zmuda of the A. de Rothschild Ophthalmological Foundation and Dr. Christine Levy-Gabriel of the Curie Institute. The subject is now of unquestionable importance and evidently of great interest to Ophthalmologists, whether they are orbital- palpebral specialists or not. Indeed, errors or delays in the diagnosis of tumor pathologies are relatively common and the consequences can be serious in the case of malignant tumors, especially carcinomas. Swift diagnosis and anatomopathological confirmation will lead to a treatment, discussed in multidisciplinary team meetings, ranging from surgery to radiotherapy. -

Differential Diagnosis of Basal Cell Carcinoma and Benign Tumors of Hair Follicles Using CD34 RESEARCH COMMUNICATION Differential Diagnosis of Basal Cell Carcinoma and Benign Tumors of Cutaneous Appendages Originating from Hair Follicles by Using CD34 Demet Sengul1, Ilker Sengul2*, Muzeyyen Hesna Astarci3, Huseyin Ustun3, Gamze Mocan4 Abstract Background and Aims: Differential diagnosis of the group of benign trichoblastomas, trichofolliculomas, trichoadenomas and trichoepitheliomas, and basal cell carcinomas (BCCs) is troublesome for the clinician as well as the pathologist, especially when only small biopsy specimens are available. Here we investigated whether CD34 expression might be of assistance. Methods: Thirty benign tumors of cutaneous appendages originating from hair follicles (BTCOHF) and 30 BCCs were retrieved from our archives and immunohistochemically stained. CD 34 expression was graded from [0] to [2+] and compared among the groups and subgroups. Results: There was no significant difference between the degree of expression between [0] and [1+] and [0] and [2+] for each group. However, [1+] and [2+] immunopositivity of BTCOHFs was significantly stronger than in BCCs (p= 0.014). Conclusions: CD34 may contribute to differential diagnosis of skin lesions.

It is an inherited autosomal dominant disorder. This syndrome also includes extra-cutaneous findings, such as pulmonary cysts, spontaneous pneumothorax, and renal cancer. Because of the systemic involvement, early diagnosis and treatment are important. Here, we report the case of a 53-year-old man diagnosed as having Birt-Hogg-Dube syndrome.

Physical examination revealed a dome-shaped, 12x13-mm, dark red tumor. The tumor was excised with a 2 to 3-mm margin. The patient has remained free of disease during 77-months of follow-up. Microscopic examination revealed a bulb-like tumor in the dermis, contiguous with the overlying epidermis. It was composed of small, monomorphous, cigar-shaped basaloid cells in linear, parallel rows, resembling the palisading of nuclei of Verocay bodies, and presenting a rippled-pattern. There were scattered cells showing sebaceous differentiation with vacuolated cytoplasm and scalloped nuclei. There were tiny, duct-like spaces. The tumor revealed characteristics of rippled-pattern sebaceoma. -

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.
