Abstract
Langerhans cell histiocytosis (LCH) is a rare disorder characterized by the proliferation of pathologic Langerhans cells. Its clinical presentation is highly variable, that range from single-system, limited disease to severe, multi-organ disease with high mortality. LCH usually affects children and young adults. The most frequent sites for LCH are the bone, skin, lung, pituitary gland, and lymph nodes. Salivary gland involvement by LCH is extremely rare, and only a few cases of LHC involving the parotid glands have been reported in the English literature. To our knowledge, the involvement of the sublingual gland as a part of single or multisystem LCH has not been previously described. Herein we reported the first case of primary LCH of the sublingual gland. A 40-year-old woman presented with a 2-month history of a painless mass on the right sublingual area. Excision of the lesion including the right sublingual gland was performed. Histopathological diagnosis of LCH was rendered. The patient remains free of symptoms 17 months after surgery.Keywords
