A 29-year-old man presented with a large, asymptomatic, brown, hyperpigmented, depressed plaque over his left upper back, which included the scapular area, since childhood. Histopathological analyses of the biopsy specimens was consistent with a rare entity known as neurovascular hamartoma. This uncommon lesion has been reported in two publications, either as a possible marker of the malignant rhabdoid tumor or as a hamartomatous tongue lesion in children. Due to its possible association with the aggressive and often fatal rhabdoid tumor, periodic examination of this lesion may be warranted.

Unlabelled: The oral hamartoma is a unique presentation of head and neck tumors with nonspecific etiology and atypical histopathological presentation. Oral hamartomas generally present as smooth, painless, pinkish masses, histologically comprising neural and vascular components intermingled in connective tissue stroma. The presence of a neurovascular hamartoma (NVH) within the oral cavity is truly a rare entity, scarcely reported in the literature.

Background: Tuberous sclerosis complex (TSC) is a multi-system genetic disease that causes benign tumors in the brain and other vital organs. The most debilitating symptoms result from involvement of the central nervous system and lead to a multitude of severe symptoms including seizures, intellectual disability, autism, and behavioral problems. TSC is caused by heterozygous mutations of either the TSC1 or TSC2 gene and dysregulation of mTOR kinase with its multifaceted downstream signaling alterations is central to disease pathogenesis.
