ABSTRACT
Background: Skin adnexal tumors (SAT) encompass a wide spectrum of benign and malignant tumors that differentiate toward one or more adnexal structures found in normal skin. Overall incidence of SATs is low yet they can be challenging to diagnose. Our study aims at analysis of histopathological spectrum of various SATs according to age, sex and anatomic locations along with histopathological features.Methods: It was a retrospective cross-sectional study conducted over a period of 2 years from June 2017 to May 2019. All cases were retrieved from department registries and analyzed.Results: Out of the total 4013 biopsies, 25 cases were diagnosed as SATs comprising 44% of tumors with eccrine sweat gland differentiation followed by tumors showing hair follicle differentiation (32%), sebaceous differentiation (16%) and apocrine gland differentiation (8%). The age ranged from 4 years to 68 years and male: female ratio was 1:1.5. Most of the tumors were benign (84%) while only 16% were malignant. Pilomatricoma (19%) was the most common benign tumor while sebaceous carcinoma (75%) was the most common malignant tumor.Conclusions: Skin adnexal tumors are relatively rare neoplasm. Malignant cases are less common than benign ones. Histopathology is quite essential for diagnostic point of view.
ABSTRACT
Background: Skin adnexal tumors (SATs) are uncommon and may cause diagnostic problems. Objective: The aim of this study is to determine the frequency of SATs with respect to their clinicopathological features over a period of 4 years. Materials and Methods: It was a retrospective, descriptive study. Formalin-fixed, paraffin-embedded sections were stained with hematoxylin and eosin for histopathological analysis and with special stains as Alcian blue/periodic acid–Schiff stain for confirmation. Results: A total number of cases that were diagnosed as SATs were 18; benign tumors were 17 (94.4%) and one malignant tumor (5.6%). Most tumors were of sweat gland origin (61.1%) followed by hair follicle origin (33.3%) then by sebaceous gland origin (5.6%). The age ranged from 3 to 51 years and male: female ratio was 1.57:1. The head-and-neck region was the most common location (44.4%). Hidradenoma (35.3%) was the most common benign tumor followed by pilomatrixoma (23.5%) and spiradenoma (17.6%) while sebaceous carcinoma was the only malignant tumor detected. Conclusion: The overall incidence of SATs was found to be very low. Benign SATs were more as compared with the malignant tumors. A careful histopathological assessment is essential for accurate diagnosis.
ABSTRACT
Background: Troublesome tumors (Skin adnexal tumors (SAT)) pose a major diagnostic difficulties because of their wide spectrum and variants, their rarity, differentiation along two or more adnexal lines and their complicated nomenclature to both the surgeon and the pathologist. Histopathology is the gold standard of diagnosis with immunohistochemistry playing a limited role.Materials and methods: A Prospective study of skin adnexal tumors (n =25) diagnosed on histopathological examination over a period of 2 years (June 2015 to May 2017). All slides were stained with H & E.Results: Majority of the patients are in the third and fourth decade. Females outnumbered the males.Twenty-two tumors are benign and 3 are malignant. Most common skin adnexal tumors are Hair follicle origin tumors comprising of 15cases (60%). In that most common benign tumor is Trichoepithelioma. Head and neck region is the commonest site involved.Conclusion: Skin adnexal tumors are relatively rare. Benign adnexal tumors are more common than the malignant lesions. Histopathology is essential to confirm the diagnosis.
ABSTRACT
Background: Histopathology is the gold standard of diagnosiswith a limited role of Immunohistochemistry. The present studywas Conducted to study the Eccrine skin Adnexal tumors withreference to their Anatomical location, age, sex of theindividuals affected to determine their incidence and correlatethem with other simulating studies.Material & Method: A total of 106 specimens of skin Adnexaltumors were received in the department of pathology fromdepartment of Dermatology, surgery and other specialties fromJune 2002 to May 2012. Histopathological Examination wasdone on routine Hematoxylin and Eosin stained tissuesections. Special stains like PAS and recticulin was donewhere required.Results: There were 21 males and 25 female patientsconstituting a ratio of 0.84 :1. The age range of these tumorswas 31-40 years with a mean age range of 43.73 years. In thepresent study 46/106 (43.39%) cases of SAT’s were of eccrinedifferentiation. Eccrine Acrospiroma was the most CommonBenign Skin adnexal tumor of Eccrine differentiationconstituting 25 out of 46 cases (54.34%) and Eccrine poromawas the least common benign Eccrine SAT. Out of 6 cases ofMalignant Eccrine skin Adnexal tumors 3/46 were of malignanteccrine acrospiroma and eccrine ductal carcinomarespectively.Conclusion: We concluded that the pattern and biologicalbehaviour of the tumors cannot be determined until thebiopsies are submitted for HPE so histopathology is mandatoryfor diagnosis SAT and to know their potential biologicalbehaviour for further management.
ABSTRACT
Panfolliculoma is an exceeding rare follicular benign neoplasm with differentiation toward both upper and lower segments of the hair follicle. In this report, we present a case of cystic panfolliculoma in the occipital region of the scalp of a 19-year-old female. We describe the histopathological and immunohistochemical features of the tumor and briefl y discuss the differential diagnoses of this rare entity.
