Rapidly Growing Superficial Angiomyxoma in Mandibular Gingiva: A Case Report and Literature Review

Solitary Superficial Angiomyxoma in an Uncommon Location: A Case Report and Literature Review

Superficial angiomyxoma (SAM) is a rare, benign, and slow-growing soft tissue tumor with a tendency for frequent local recurrence. Most SAMs are solitary and sporadic. However, multiple SAMs, particularly on the external ear or eyelids, may be the initial or only sign of the Carney complex, an autosomal dominant syndrome that impacts various organs, including the heart, breasts, and skin, and is linked to endocrine hyperactivity. To ensure an accurate diagnosis, a comprehensive patient interview, physical examination, and laboratory tests, including endocrine-specific markers and imaging studies, are essential. Due to the high risk of recurrence, especially in large, encapsulated lesions, complete surgical excision is the preferred treatment approach. We present a case of a 24-year-old female with SAM on the shoulder, review the relevant literature, and discuss the pathogenesis and appropriate management of such cases.

A Case of Profound Obstructive Sleep Apnea Secondary to an Unrecognized Lingual Angiomyxoma

A 44-year-old woman presented to the emergency department status post incidental discovery of a large lingual mass identified during workup of a known intracranial neoplasm. The patient presented with a 4-month history of progressive altered mental status, somnolence, aphasia, and dysphagia; symptomology was attributed to the suprasellar tumor. Metastatic disease to the oral cavity was the primary differential diagnosis. Imaging demonstrated a 5.5 × 5.5 cm posterior tongue mass with near complete pharynx obstruction. Prompt debulking and pathology workup occurred. On postoperative day 1, the patient experienced complete resolution of all symptoms. Given rapid improvement, neurological decline was ultimately attributed not to the suprasellar mass but instead as being secondary to profound obstructive sleep apnea and ensuing sleep deprivation caused by the lingual tumor. This case describes the rare finding of a massive lingual superficial angiomyxoma with a synchronous cerebral neoplasm in which the latter functioned as a diagnostic distraction.

A rare case of solitary intraoral superficial angiomyxoma arising in the soft palate

Superficial angiomyxomas are myxoid mesenchymal tumors, and intraoral superficial angiomyxoma is extremely rare. This paper reports a novel case of a 41-year-old Japanese male patient with a 32 × 22 mm superficial angiomyxoma in the right soft palate. Tumor resection was performed and a polyglycolic acid sheet was attached. Over a 28-month follow-up, there was no evidence of disease recurrence. This paper also reviewed 11 cases of intraoral superficial angiomyxomas reported in previous literature. The condition was more common among middle-aged men. Surgical resection was the most common treatment, and local recurrence was observed in only one case.
