The follicular variant of Becker\'s nevus is an under-reported entity. We present the rare occurrence of follicular Becker\'s nevus in 7 patients, confirmed through dermoscopy and histopathological examination. Dermoscopy shows perifollicular hypopigmentation surrounded by a well-defined net-like pigmentation corresponding clinically to the presence of folliculocentric macules. Histology shows prominent basal and suprabasal melanization surrounding the follicle, corresponding to well-defined net-like pigmentation seen on dermoscopy. However, the melanization does not extend along the entire length of the follicular epithelium leading to perifollicular hypopigmentation on dermoscopy. Though biopsy is confirmatory, it is not usually necessary.

Nevus is a group of melanocytes that grow together to form a benign growth on the skin. It is often a black lesion that may protrude from the skin. Becker\'s nevus is a hyperpigmented lesion that presents congenitally or is acquired. The pigmentation and unusually high hair growth might grow darker with time. Becker\'s nevus, which can interchangeably be called Becker\'s melanosis, is a rare disease usually presented by men. The following case is of a 21-year-old male who presented with a hyperpigmented lesion on his right arm. The lesion started at age 16 and increased in size gradually; it involved the flexor surface of the right elbow joint and showed hypertrichosis with irregular margins. On examination, the top dermis contained melanophages, and the basal layer was hyperpigmented. Based on clinical appearance and examination, Becker\'s nevus was diagnosed.

Becker\'s nevus (BN) is one of the cutaneous hamartomatous lesions that often presents as an acquired, single unilateral pigmented hairy patch on the upper trunk, scapular region, or upper arm. Hereby we introduce a 13-year-old girl with the unusual manifestation of BN with multiple acquired, pigmented hairy patches for six months without any musculoskeletal or developmental involvements. After carefully reviewing the literature, to the best of our knowledge, this is the first case in this regard in Iran.

Becker\'s nevus (BN) is an acquired unilateral hyperpigmented hairy macule, whereas morphea is a chronic connective tissue disease of unknown etiology, characterized by skin thickening with increased quantities of collagen in the indurated lesion, usually involving the upper trunk and proximal extremity. The occurrence of both disease in the same anatomical site and individual was not reported previously. We report this rare case in a 17-year-old, Indian girl and was diagnosed after clinical histopathology and dermoscopic correlation. Morphea can be an interesting incidental occurrence within a large plaque of BN.
