Abstract BACKGROUND: Appendageal skin tumors belong to a heterogenous group of tumors with specific histopathology. The aim of this study is to determine the pattern of appendageal tumors in skin biopsies done in our department. METHODS: This is a 3-year retrospective descriptive study of all patients who were diagnosed to have skin appendageal tumors in our department, and the diagnoses were confirmed by histopathology. The tumors were classified as eccrine, hair, sebaceous, and apocrine after a detailed examination of routine hematoxylin and eosin sections. RESULTS: The total number of cases in the study was 33-10 males and 23 females. Tumors with eccrine differentiation constituted the maximum, 17 cases (51.5\%); followed by tumors with hair differentiation, 12 cases (36.36\%); tumors with sebaceous differentiation, 2 cases (6.06\%); and apocrine tumors, 2 cases (6.06\%). Syringoma constituted the commonest eccrine tumor, 14 cases (42.42\%); while trichoepithelioma was the commonest hair tumor, 9 cases (27.27\%). The other eccrine tumors were eccrine spiradenoma, 2 cases (6.06\%); and nodular hidradenoma, 1 (3.03\%). The other hair tumors were pilar cyst, 2 (6.06\%); and pilomatricoma, 1 (3.03\%). The sebaceous tumors constituted 2 cases (6.06\%) of nevus sebaceous. Syringocystadenoma papilliferum, 1 (3.03\%); and cylindroma, 1 (3.03\%), constituted the apocrine tumors. CONCLUSIONS: Appendageal skin tumors are relatively uncommon. Histopathology is mandatory for the diagnosis. No tumor showed malignant change in this study.
