Two entities in angiolipoma. A study of 459 cases of lipoma with review of literature on infiltrating angiolipoma

Intraoral approach for the treatment of non‑infiltrating angiolipoma of the floor of the mouth in an elderly patient: A case report with review of the literature

A 75-year-old male patient visited Gangneung-Wonju National University Dental Hospital (Gangneung, South Korea) with a 35-mm fluctuant lesion on the floor of the mouth. It was a dome-shaped exophytic lesion with its top on Wharton's duct orifice area. The encapsulated lesion was excised cautiously and the final diagnosis was non-infiltrating angiolipoma. To the best of our knowledge, this is the first report of an intraoral approach for the treatment of a non-infiltrating angiolipoma on the floor of the mouth in an elderly patient. Differentiating it from a ranula is essential for the surgical approach and, as there is a higher transition to infiltrating angiolipoma, definite treatment should be considered in elderly patients.

Subcutaneous angiolipoma in the scrotum: A case report

BACKGROUND

Angiolipoma has been reported in many cases, and it often occurs in the skin of the trunk and limbs. However, angiolipoma in the scrotum is a rare disease with unknown etiology. This condition is difficult to diagnosis with other lumps in the scrotum.

CASE SUMMARY

A 32-year-old man presented to the urinary department with a history of an enlarged left scrotum with increasing discomfort for about 5 years. Physical examination revealed that there were a palpable mass measuring about 7.0 cm × 6.5 cm in the left scrotum, with smooth surfaces but without tenderness or adhesion to the skin. Ultrasound showed that there was a hyperechoic mass under the skin of the top scrotum, about 72 mm × 64 mm × 21 mm in size, with clear borders, uneven internal echo, and abundant blood flow signals. Serum human chorionic gonadotropin and alpha-fetoprotein were in normal level. Subcutaneous mass resection at the bottom of the left scrotum was performed under local anesthesia with 1% lidocaine. Postoperative pathological examination resulted in a diagnosis of subcutaneous angiolipoma of the scrotum. No evidence of recurrence was found at 6 mo after surgery and there were no complaints of discomfort.

CONCLUSION

Angiolipoma is an extremely rare type of benign tumor extremely rarely found in the scrotum, but needs to be considered when evaluating scrotal masses especially when the mass is solid. According to the characteristics of angiolipoma, surgical resection is the best treatment strategy and it is not prone to recurrence after resection.
