Epithelioid Variant of Pleomorphic Liposarcoma: A Rare Challenging Diagnosis Causing Severe Medial Thigh Pain.

We present the case of pleiomorphic liposarcoma in the medial compartment of the thigh of a 59-year-old female patient. The lump was noticed eight months prior to presentation and had gradually increased in size, leading to pressure symptoms in her thigh. Although painless initially, the lump eventually became tender prompting her to seek surgical attention. At the plastic surgery clinic, she was advised to get an MRI, which revealed an irregular but well-defined mass lesion measuring 8.2 x 6.6 x 4.3 cm. The mass did not have any manifestations in the surrounding structures. A wide excisional biopsy was then performed, and multiple sections were processed for histopathological analysis, confirming a diagnosis of epithelioid variant of pleomorphic liposarcoma.

Giant renal angiomyolipoma.

A 65-year-old woman from a rural area presented to the surgical service with a very large abdominal lump that the patient had first noticed 8 years previously. The lump had steadily increased in size over time, and the patient had dysuria, weakness and dyspnoea on exertion. On examination she was grossly anaemic with a large retroperitoneal lump that occupied the whole right side of abdomen; the lump was soft to firm in consistency and non-tender. She had no lymphoedema or other palpable lymph nodes. Ultrasound revealed a large retroperitoneal tumour with fatty elements, arising from the right kidney. There was no involvement of the intestines. Findings of the computed tomography scan were typical for renal angiomyolipoma. The patient underwent surgery and the tumour was excised. Four units of blood were transfused preoperatively and in addition two units were given postoperatively. The patient was given thromboprophylaxis perioperatively and in the postoperative period because she was bedridden and could not ambulate. She made an uneventful recovery.
