ABSTRACT
INTRODUCTION: Renal angiomyolipoma is considered a benign mesenchymal tumor composed of fat, smooth muscle, and blood vessels. It represents 1-3% of solid renal tumors. Despite this tumor's benignity, it can be aggressive with a locoregional extension. CASE REPORT: A 41-year-old north African caucasian woman consulted with chief complaints of right lower back pain with no hematuria and no urinal sign. Thoracic-abdominopelvic contrast-enhanced computed tomography showed a right inferior polar heterogeneous renal mass complicated with venous thrombus ascending to the right atrium level. The patient underwent radical nephrectomy under extracorporeal circulation and direct supervision of the fatty thrombus at the right atrium level. The postoperative period was uneventful. The final histologic examination was concordant with renal angiomyolipoma. CONCLUSION: Renal angiomyolipoma is the most common benign kidney tumor. Despite its benignity, it can be associated with lethal complications such as hemorrhage, and it can also show signs of local extension mimicking malignant tumors. The cornerstone of the treatment remains surgery.

BACKGROUND: Darier-Ferrand dermatofibrosarcoma (DFS) is a rare malignant cutaneous neoplasm characterized by local aggressiveness, high risk of recurrence, and low metastatic potential. CASE PRESENTATION: A 60-year-old Tunisian man with recurrent abdominopelvic DFS for which he had undergone multiple excisions presented with an extensive DFS that invaded the external genitals. He underwent a large excision with emasculation and thin cutaneous graft of the abdominal wall and local skin flap in the pelvis. CONCLUSION: DFS is a rare yet recurrent skin tumor. Wide excision with free margins remains the cornerstone of treatment. We report a case of a giant DFS treated with wide excision and reconstructive surgery to cover the defect.

BACKGROUND AND AIM: Breast tuberculosis is a rare disease, even in endemic areas. The diagnosis can be challenging, as it can mimic breast cancer. We aim to report our experience and discuss diagnoses and management modalities. RESULTS: We encountered twelve cases of breast tuberculosis in our institution from 2004 to 2019. The average age of our Caucasian North African patients was 42 years old (22-63). The classic presentation was a breast lump found in half of the cases. On physical examination, we suspected breast carcinoma in seven patients. The average size of the tumors was 39 mm (15-80 mm). Nine patients had a mammogram. In five cases, there was a suspicious breast mass mimicking a malignant tumor with an average size of 33 mm (25-60 mm). A ultrasonography was performed in 6 cases and revealed a suspicious ill-circumscribed nodule in four patients with an average size of 37.5 mm (10-60 mm). Five patients had a lumpectomy, and seven women underwent drainage of the abscess and the biopsy of its hull. The association of epithelioid cell granulomas and caseous necrosis was mandatory for the histological diagnosis of tuberculosis. All of them had an antitubercular therapy. The median period of follow-up was of 43 months (3-156 months). One patient presented with a recurrent abscess of the breast. CONCLUSION: Our study found that clinical examination and radiological imaging were not specific. Positive cultures for Koch bacillus or histological confirmation are mandatory for the diagnosis. A meta-analysis of the existing cases is needed.
