Adult type rhabdomyoma in a child

Recurrent adult-type rhabdomyoma: a rare differential diagnosis of "swellings in the masticatory muscle"

Rhabdomyomas are rare benign mesenchymal tumors with skeletal muscle differentiation and a predilection for the head and neck area. A 38-year-old man presented with persistent, slowly growing, painless swelling in the left inner cheek for 2½ years. The lesion was detected during routine dental examination and was considered to represent a mucocele. The mass was removed via a transoral surgical approach, followed by a local recurrence 6 months later that was again surgically removed. The patient is alive and well 2 months after last surgery. Adult-type rhabdomyoma is a rare, occasionally recurring, benign mesenchymal tumor that should be included in the differential diagnosis of submucosal swellings in the oral cavity including the masticatory musculature. Adult-type rhabdomyoma of the cheek and masticatory area are exceptionally rare with no more than 3 cases reported to date.

Rhabdomyomas of the submandibular and sublingual glands

Rhabdomyomas are rare benign mesenchymal tumors distinguished in cardiac and extracardiac forms. Extracardiac rhabdomyomas are classified as adult type, fetal type, and the genital type. Adult extracardiac rhabdomyomas are mostly found in the head and neck and usually present a slow growth. We report a case of a patient with a manifestation in the submandibular and sublingual glands.
