Skin appendix tumors are rare and highly varied tumors. Are mostly benign characters, rarely malignant and dominated from the morphological point of view by their lesional polymorphism. These tumors may present with follicular, apocrine/eccrine, sebaceous and sometimes mixed differentiation, posing diagnostic problems. The aim of this study is to describe the epidemiological profile and the different anatomopathological aspects of this group of tumors and to compare them with data from the literature. We carried out a descriptive study with a retrospective stage, of 35 cases of cutaneous adnexal tumors collected at the service of the Central Laboratory of Pathological Anatomy and Cytology of Ibn Sina Hospital, CHU of Rabat during a period of 3 years, from 2019, 2020 and 2021. The result of this study shows the peak frequency of these lesions, which is located between 60 years and older, occupying 34.2% of all cases; the average age of the patients studied is 41 years and we find the predominance of the female sex which corresponds to 62.9% of the cases; the predilection seat of the lesions is the region of the head and neck, which is occupied by 51.4%; tumor differentiation is divided into apocrine/eccrine which represents 68.6% of cases; follicular in 20% of cases and sebaceous in 11.4% of cases; the most common histological type is poroma 25.7% followed by pilomatricoma 14.2% and papilliferous syringocystadenoma 11.4%; benign tumors are frankly in the majority, occupying 91.5%, against 8.5% of malignant tumors.
