RESUMEN
Adenomyoepithelioma represents a rare tumor of the breast characterized by biphasic proliferation of epithelial and myoepithelial cells. Owing to its nonspecific clinical presentation, the rarity, and the morphological pitfalls in differential diagnosis, the diagnosis may be extremely difficult especially on limited samples such as core needle biopsy; thus, the diagnosis is histological, which is confirmed by the specificities of the immunohistochemical analyses. Here we report a case of a 64-year-old female who presented a benign adenomyoepithelioma diagnosed on core needle biopsy, review the clinicopathological features of breast adenomyoepithelioma diagnosed on core needle biopsy, and discuss the useful clues to prompt accurate diagnosis.
RESUMEN
Rectal carcinoma with metastasis to skeletal muscle is a rare occurrence. Since 1970, only 30 cases of skeletal muscle metastasis originating from colorectal adenocarcinomas have been documented, underscoring its exceptionally low incidence. Here, we present the case of a middle-aged man who was diagnosed with rectal adenocarcinoma 3 months ago. During examination, a subcutaneous mass was discovered in the left proximal buttock. Histological analysis of a biopsy confirmed that this mass was a metastatic lesion originating from the primary rectal adenocarcinoma.
RESUMEN
Perirenal hematoma is a common complication of traumatism and renal procedures such as nephrostomy, angiography, and lithotripsy. It may constitute a challenging diagnosis in a pre-existing tumor context or in case of an atypical imaging appearance. We present a female patient followed for cervix cancer, who developed bilateral perirenal hematoma with an atypical MRI appearance evoking a malignant tumor. The diagnosis is established by the association of different imaging data (MRI with diffusion and ADC, CT scan without contrast, and CT scan after injection of contrast product). Percutaneous drainage remains the best management option for the perirenal hematoma in hemodynamic stable patients.
RESUMEN
Adenoid cystic carcinoma is a rare tumor that typically originates from secretory glands, most commonly found in the salivary glands. However, it can also develop as a primary cutaneous adenoid cystic carcinoma, which appears identical under the microscope to adenoid cystic carcinoma originating in other tissues. Distinguishing between primary cutaneous adenoid cystic carcinoma and extracutaneous adenoid cystic carcinoma with cutaneous metastases is crucial for determining the prognosis and appropriate management of the condition. In this case report, we describe a case of primary cutaneous adenoid cystic carcinoma located on the hand with lung metastases. Proper differentiation, treatment planning and regular clinical follow-up to monitor for any signs of recurrence or metastasis are essential to ensure favorable outcomes for patients with this rare neoplasm.
RESUMEN
The fistulization of a hepatic hydatid cyst to the duodenum is an extremely rare case demonstrated in computed tomography and confirmed surgically. We reported a case of 56 years-old woman representing this unusual complication. We show, through this work, the importance of radiological signs that can help to make the diagnosis before surgery.
