Pilar leiomyoma is a benign smooth muscle tumor arising from the arrector pili muscle, it is representing 3 to 5% of leiomyoma lesions [1]. Segmental distribution of pilar leiomyoma is common. However, multisegmental distribution is rare [2]. We report an exceptional case presenting unilateral and multisegmental localization in a young man. The treatment can be difficult whene it’s a multiple and painful. Various pharmacological options might include nifedipine, doxazocine, gabapentine, and Topical 9% hyoscine hydrobromide have been used to relieve the pain associated with these tumors [2].

Our case was 24-year-old man. Along 3 years, he presented a multiple pink papules and nodules. Some lesions were slightly pigmented and localized at the level of the right half of the thorax (Fig. 1) and the posterior and anterior of the homolateral arm (Fig. 2). The patient reported intense pain especially during the cold weather stages. The dermoscopy did not show any specific signs except generalized hypopigmentation with a pale and pink appearance in some lesions (Figure 3). The histology confirmed a pilar leiomyoma. The renal ultrasound was unremarkable and the patient was treated by Nifedipine to relieve pain.
