الوصف: Becker’s nevus is a cutaneous smooth muscle hamartoma characterized by a unilateral, hyperpigmented, and hypertrichotic patch that commonly affects the upper trunk. It most commonly presents during puberty and sometimes it may be present since birth. We, hereby, report a case of late onset bilateral Becker’s melanosis over the scalp which is an unusual site.

الوصف: Abstract Background Hamartoma is a benign, tumor-like proliferation of mature tissue that is natural to the organ from which it developed. Oral hamartomas are rare and can occur as an isolated finding or as a part of a syndrome. Case presentation We report a 4-day-old male neonate who was postnatally noted to have a large 3.5 × 3.5 cm lobulated mass over the tip of the tongue. The mass was causing protrusion of the tongue and feeding difficulties following which surgical excision was planned. The postoperative recovery was uneventful. Conclusion Although rare, lingual hamartomas should be considered in the differential diagnosis algorithm for congenital tongue lesions. The definitive diagnosis is histopathological with complete resection of the tumor resulting in a favorable prognosis.

الوصف: Smooth muscle hamartoma are usually solitary and congenital, may affect the genital area and nipples. Histopathologically, they are characterized by the presence of mature smooth muscle bundles. We present a 40 year-old male with bilateral nipple enlargement excised with clinical suspicion of bilateral leiomyoma. Skin biopsy shows mature, irregularly arranged smooth muscle bundles and lactiferous ducts between them. Immunohistochemistry is positive for smooth muscle actin, desmin and fumarase, but negative for estrogen and progestogen receptors. The presence of lactiferous ducts excludes bilateral leiomyomas. Even when, histopathologically, this can be interpreted as the nipple-type of muscular hamartoma of the breast, clinical history favors an anabolic drug-induced lesion. Bodybuilders present gynecomastia and nipple enlargement as frequent problems, but we have not found any histopathological description of these nipple lesions. We consider that dermatologists should be aware of the presence of them and dermatopathologists should know their histopathological features to avoid misdiagnosis as neoplasms.

الوصف: Background: Acquired smooth muscle hamartoma (ASMH) is a rare benign lesion characterized clinically by hyperpigmented plaques with hypertrichosis and some follicular papules. The main histologic finding is the presence of disorganized smooth muscle bundles in the dermis. Only 25 cases of ASMH have been reported in the literature. Clinical case: We present the case of an 18-year-old male who reported a pigmented area and increased hair growth on the left hemifacial with one year of evolution. Clinically, a plaque was observed in the preauricular region and on the left cheek with a linear Blaschkoid path, consisting of hyperpigmentation, hypertrichosis, and some papular lesions, with negative pseudo-Darier sign. Histological analysis showed an increase in the number of smooth muscle bundles in the middle and deep dermis surrounding abundant sebaceous glands and numerous hair follicles in different stages of evolution. Conclusions: The sebaceous component in this lesion was prominent. Therefore, we considered this lesion part of a spectrum where the acquired smooth muscle hamartoma and folliculosebaceous cystic hamartoma are found at the extremes. This case would fall in the middle of the range, as it combines both histological features.

الوصف: International audience ; Background: Patients with epidermal nevi strongly demand cosmetic improvement. Laser treatment appears appealing and is frequently used in clinical practice. Nevertheless, large series with long-term follow-up are missing, preventing definitive conclusions about its real benefit.Objective: To evaluate the long-term effectiveness and safety of lasers for epidermal nevi.Methods: Bicentric, retrospective, cohort study, including all patients treated with a laser for an epidermal nevus with more than a 1-year follow-up.Results: Seventy patients were treated for different types of epidermal nevi, mostly with ablative lasers: 23 verrucous epidermal nevi, 16 nevi sebaceous, 26 Becker nevi, 2 inflammatory linear verrucous epidermal nevi, 1 smooth-muscle hamartoma, 1 rounded and velvety epidermal nevus, and 1 nevus lipomatosus superficialis. The follow-up period was a median of 37 months (range, 12-127 months). Better results, fewer recurrences, and higher patient satisfaction were noted in treatments for verrucous epidermal nevi than for nevi sebaceous. Q-switched lasers failed to show any degree of improvement in almost all patients with Becker nevus.Limitations: The retrospective nature of the study.Conclusions: Ablative lasers can treat verrucous epidermal nevi with good long-term esthetic results but have limited long-term efficacy for nevus sebaceous. Q-switched lasers failed to improve Becker nevi.

الوصف: Smooth muscle hamartoma (SMH) is a proliferative disorder of cells originating from muscle cells. It is a benign tumoral mass that usually presents as a single congenital skin-colored and hypertrichotic plaque involving the trunk and extremities. Multiple SMHs have rarely been reported in the literature. We describe the case of a seven-month-old girl with multiple SMHs located over the back and arm areas. The diagnosis was confirmed by biopsy and immunohistochemical (IHC) staining. She had no cerebral or skeletal abnormalities and her growth and development were normal.

الوصف: Congenital smooth muscle hamartoma is a benign proliferation of smooth muscle that most commonly presents in the lumbosacral area or proximal extremities. Although exceedingly rare, congenital smooth muscle hamartomas have been reported to occur in ocular structures such as the brow, eyelid, and conjunctival fornix. This case describes an atypical congenital bulbar lesion in a newborn male which obscured the cornea. The lesion, which appeared to originate from the bulbar conjunctiva and/or the limbus, was excised at 5 months of age. Pathologic evaluation was consistent with congenital smooth muscle hamartoma. The authors of this report believe it is the first to describe a patient with a congenital smooth muscle hamartoma of the bulbar conjunctiva/limbus.
