Histomorphological Study of Skin Adnexal Tumors andReview

Introduction/Context: Neoplasms of skin appendages are infrequently encountered in practice. Histopathologyisthe gold standard investigation for the final diagnosis. Aim of the Study: Approach to the diagnosis of skinadnexaltumors on the basis of histomorphological patterns and cell morphology. Materials and Methods: Thepresentstudy is a retrospective study done in the department of pathology. All cases are collectedfrom2004–2018, totalof 14 years retrospective study. Inclusion Criteria: All skin biopsy diagnosed as skin adnexal tumors. ExclusionCriteria: Inflammatory condition, inadequate biopsy, Cyst and tumor like lesions. Results: Total 90casesofskinadnexal tumors were included in the present study. Out of 90 cases, 42 (47%) are male patients and48(53%)arefemale. According to histomorphological pattern, 78% have solid patterns, 17%have solidandcystic, andrestare cystic. As per cell morphology, basaloid cells forms predominant in skin adnexal tumors with50%ofcases. Discussion: In the present study, a new concept of histomorphological pattern is included, whichis rarelystudied.The histomorphological pattern is classified into solid, solid and cystic and predominant cystic pattern. Solidpatternconstitutes 78% of adnexal tumors. It is predominantly seen in eccrine gland tumors like Eccrinespiradenoma,Eccrine hidradenoma. Cystic pattern is seen in 5% of adnexal tumors. It is seen in pilar tumors likepilomatrixoma,trichoepithelioma. Solid and cystic pattern is seen in 17% of adnexal tumors. It is seeninbotheccrine, apocrineand pilar tumors. Conclusion: Hence, combining the histomorphological pattern andcellular morphologyhelpspathologist to diagnose with ease.
