Intramuscular hemangioma (IMH) represents less than 1% of all hemangiomas. In the head and neck region, it occurs mostly in the masseter, temporalis and sternocleidomastoid muscles. Despite its infiltrative growth pattern and several worrisome histological features, such as increased mitotic activity, plumpness of the nuclei, intraluminal papillary projections or perineural infiltration, the lesion is benign, and complete surgical excision is the preferred treatment for such oral lesions.Herein, we report three rare cases of IMH in the tongue and lip, discuss the clinical and histological aspects, and review the literature regarding this lesion.

White sponge nevus (WSN) is an uncommon benign inherited disorder characterized bywhite and diffuse painless lesions in oral, esophageal, or genital mucosa. The lesions may develop at birth or later in childhood or adolescence, with careful clinical examination being sufficient for diagnosis in most cases. However, microscopic analysis may be necessary particularly in adults in which other whitish oral lesions may be clinically suspected.Dermatologists, dentists, and pathologists should consider WSN when evaluating multiple white oral lesions, thus preventing unnecessary treatments. Herein, we report four additional cases of WSN with emphasis on its clinical and histopathological features. K E Y W O R D S oral mucosa, white lesions, white sponge nevus
Brazilian oral pathology laboratory, while maintaining, as effectively and humanely as possible, high-quality oral diagnoses for this population in Rio de Janeiro. All efforts were made to try to avoid delays in the treatment of oral cancer patients, providing a modicum of relief to some of the peaceful Brazilian people who do not deserve such a high number of deaths and such disrespect for public health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
