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.

Cardiac myxoma in its morphology is a typical benign tumor, meanwhile, the fact of its localization in the heart chamber, directly in the constant blood flow, largely determines the clinical behavior of this neoplasm, which is often manifested by the development of characteristics that formally determine the aggressive and even malignant nature of the course. Accordingly, the malignancy of cardiac myxoma is determined more by its clinical behavior (recurrence, multifocality of the lesion, the presence of mechanisms of spread similar to metastasis) rather than by its histological picture. In the structure of primary benign tumors of the heart, myxoma occupies a dominant position and its incidence is up to 85%.

Superficial angiomyxoma is a benign neoplasm of mesenchymal origin that affects both sexes with a slight predilection for males. It can present in a solitary or multiple form, within the framework of the Carney complex, an autosomal dominant syndrome characterized by the triad: cutaneous and cardiac myxomas, skin pigmentation and endocrine overactivity. They occur more commonly in the head and neck, trunk and lower limbs; the location in the genital region and particularly in the scrotum is very unusual.

Superficial angiomyxoma is an infrequent benign soft tissue tumor, clinically presented as slow-growing, painless cutaneous, or subcutaneous mass. It is mostly described in middle aged population with preference location in trunk, head, neck, and genitalia. Herein, we report a rare growth variant of a solitary superficial angiomyxoma with uncommon site of occurrence in a 39-year-old female.
