A case of migratory stomatitis in a young male patient: Management and differential diagnosis.

Migratory stomatitis (MS) is an uncommon inflammatory condition with unclarified etiology, which despite its benign nature, may raise concerns for patients and diagnostic difficulties for professionals. This case report aims to describe the clinical features of a patient who presented with MS in conjunction with benign migratory glossitis (BMG), and its diagnostic process and management. The patient, a 25-year-old man, sought diagnosis of an oral condition, with cyclic behavior, which had been causing him great discomfort for a year. The patient presented erythematous patches on his lower lips and right side of the buccal mucosa, surrounded by a slightly elevated halo with a concomitant classical picture of BMG. After analysis of his entire symptomatology, the diagnosis of MS associated with BMG was concluded. The patient received clear explanations and symptomatic treatment. The diagnosis of MS may be challenging, even to oral medicine practitioners, especially if it occurs alone. MS with concurrent manifestation of BMG may make the conditions easier to diagnose, but it does not exclude the need to apply a complete process of differential diagnosis to rule out other similar possibilities.

An Atypical Presentation of Sinonasal Tract Alveolar Rhabdomyosarcoma in a Young Male Patient Submitted to Multimodality Treatment.

Rhabdomyosarcoma (RMS), a malignant tumor derived from the neoplastic proliferation of striated skeletal muscle cells, is the most common pediatric soft tissue sarcoma. Its treatment is mainly based on neoadjuvant chemotherapy (QT+), surgical resection, and adjuvant radiotherapy (RT+). RT+ has shown satisfactory results for locoregional control of the disease, in spite of promoting local side effects. The present case report was aimed at describing the clinical and therapeutic characteristics and the management of complications resulting from multimodal therapy in a patient with an atypical presentation of RMS in the sinonasal tract. A 20-year-old Afro-descendant man complained of an expansive tumor lesion, with left eye proptosis that reduced visual acuity and caused severe regional pain. Imaging analysis showed an extensive and infiltrative lesion in the periorbital region, sinonasal tract, left maxilla, and orbital roof. According to the histopathological analysis, the diagnosis was established corresponding to parameningeal alveolar RMS that was unresectable. Treatment was initiated with three cycles of QT+ which showed partial response and later RT+. After completing half of the RT+ sessions, the patient showed a complete response with reduction in tumor volume and improvement in pain and local conditions. Side effects such as alopecia and dermatological changes induced by radiation were observed. Moreover, painful erythematous areas were observed in the region of the hard and soft palate, uvula, and oropharynx, compatible with Grade 2 mucositis lesions. After the cytological swab test, some of them were diagnosed as herpes simplex lesions; thickening and decrease in salivary flow were also found. A local drug therapy approach was instituted, and photobiomodulation was performed to manage oral complications. RT+ was shown to be effective in locoregional control of the disease; however, the early management of its undesirable effects on the surrounding tissues was required.
