Abdominal cerebriform intradermal nevus in a 22 years old female in the Eastern Region of Democratic Republic of Congo, A psychodermatological case report

Cerebriform intradermal nevi (CIN) are a rare subtype of intradermal melanocytic nevi, distinguished by their characteristic surface morphology that resembles the gyri and sulci of the human brain. Typically presenting as benign skin lesions, these nevi occur predominantly as congenital formations, often evident at birth or during early childhood.Females are more affected. CINs generally manifest in areas such as the scalp and face and can be mistaken for malignant conditions due to their distinctive appearance and potential for growth, which may be influenced by hormonal changes, particularly during puberty and pregnancy. An early diagnosis is crucial due to the associated risk of malignant melanoma, with lifetime incidence rates of melanoma in CINs ranging from 6.3% to 12%. Diagnosis is primarily clinical, supported by dermoscopy and, in uncertain cases, histopathological examination. Treatment options depend on factors such as cosmetic concerns and suspicion of malignancy, with complete excision being the most common intervention. This case report details a 21-year-old female patient with a cerebriform lesion on her flank, exacerbated by postpartum hormonal changes. The report highlights the psychological impact of such skin conditions, as the patient experienced anxiety and depression related to her lesion. Following a successful excisional biopsy and psycho-educational support, her mental health improved significantly. This case emphasizes the importance of recognizing the psychological implications of CINs and adopting a biopsychosocial approach to patient management to ensure optimal outcomes and patient satisfaction.
