Purpose: To summarize the clinical, histopathological and therapeutic features of senile gluteal dermatosis.
Patients and Methods: Retrospective analysis of 230 cases who visited the outpatient clinic of Hangzhou No. 3 People’s Hospital for skin lesions on the buttocks and hips from 2018.8– 2023.8 were included in the study, basic clinical information was collected, and they were subjected to physical examination of the buttocks and hips, and 36 cases were senile gluteal dermatosis, of which 7 underwent histopathological biopsy.
Results: A total of 230 patients were included, of which 36 were diagnosed with geriatric buttock dermatosis, with a mean age of (84.2± 12.6) years, mean body mass index of (21.7± 3.8) kg/m2, and a male to female ratio of 2:1. There was a significant correlation between the occurrence of the disease and age, gender, body mass index, sedentary time, type of chair used, and hypertension (P< 0.05). The severity of the lesions may be associated with longer sitting time and prolonged use of bamboo chairs (P< 0.05). Histopathologic changes were not specific. The skin lesions could subside after general treatment such as improvement of lifestyle, use of pressure-reducing air mattresses, salicylic acid cream, and moisturizing creams.
Conclusion: Senile gluteal dermatosis is a common senile physical dermatosis, mainly manifested as brownish scaly plaques, erythema and crusted ulcers, which can often be cured under reasonable treatment.
