Unusual Unique Renal Metastasis of Rectal Carcinoma.

Rectal cancer Is a Common malignant pathology; its usual spread in volves the liver and lungs. The occurrence of renal metastases is exceptional. CT scanning aims to evaluate extension and may incidentally reveal a renal mass, which can be better characterized through MRI and ultrasound. We describe a case of a solitary renal metastasis from rectal cancer and underscore the significant role of imaging in positively diagnosing this uncommon pathology.

Bilateral perirenal hematoma simulating metastasis.

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.

Imaging of an exceptional urinoma complicating a cervical cancer and leading to death: A case report.

Spontaneous urinoma is a rare urological complication that can occur following acute urinary obstruction. It involves a collection of urine that typically forms around the kidney as a result of rupture of the fornix. There are several causes of acute urinary stasis, including lithiasis, tumors, prostatic hypertrophy, and others. We present a unique case of an asymptomatic spontaneous urinoma discovered incidentally during the extension study of a 66-year-old woman with cervical cancer. The positive diagnosis was made through a combination of ultrasound and uro-computed tomography scan. The evolution was marked by the occurrence of a uremic encephalopathy, leading to death before any treatment.

Left ovarian mass revealing multivisceral lymphoma.

Lymphoma encompasses a range of cancers originating in the lymphatic system, categorized into Hodgkin lymphoma and non-Hodgkin lymphoma. Hodgkin lymphoma classically present as nodal disease, whereas non-Hodgkin lymphoma tends to involve extranodal regions. While it can be part of a systemic lymphoma, isolated nodal involvement is not uncommon. Extranodal lymphoma can affect virtually any organ or tissue, with the spleen, liver, gastrointestinal tract, pancreas, abdominal wall, genitourinary tract, adrenal glands, peritoneal cavity, and biliary tract being among the most commonly involved sites, in decreasing order of frequency. We present a case involving a 54-year-old woman presented with left iliac fossa pain. A sonography was performed, which showed left pelvic mass, magnetic resonance imaging showed left ovarian mass with enlargement of the cervix. Computed tomography revealed enlargement of the pancreas and adrenal glands, along with masses in the kidneys associated with extensive pathological lymph node enlargement in the para-aortic and pelvic regions. The patient underwent biopsy of a para-aortic lymph node, which revealed a diffuse large B cell lymphoma.

An unusual metastatic site of renal cell carcinoma: A case report.

The main metastatic sites of renal cancer are the lungs, bone, liver, and brain. Dissemination of clear cell renal carcinoma to the rectum is very rare, with only a few sporadic cases published in the literature. The clinical presentation is usually dominated by lower gastrointestinal haemorrhage. We report the 5th case in the literature of a rectal metastasis of clear cell renal carcinoma, revealed by a lower gastrointestinal haemorrhage occurring 8 years after the initial nephrectomy.

A rare metastasis of an ovarian adenocarcinoma occurring 13 years later: A case report.

The pancreas is a more common metastatic site for renal carcinoma; however, metastatic spread of ovarian carcinoma to the pancreas is very rare, with only a few sporadic cases published in the literature. The clinical presentation is usually dominated by epigastric pain. We report a rare case of pancreatic metastases occurring approximately 13 years after a bilateral hysterectomy with salpingo-oophorectomy for bilateral serous ovarian carcinoma.

A rare encounter in the nasopharynx: Extramedullary plasmacytoma.

Extra-medullary plasmacytoma (EMP) is a rare tumor that most frequently occur in the head and neck region, with the paranasal sinuses, nasopharynx and tonsils being the most common sites. Diagnostic criteria for EMP include histological confirmation of a solitary plasma cell lesion, the presence of fewer than 5% plasma cells in the bone marrow, and the absence of end-organ damage commonly associated with multiple myeloma. CT scans and MRI features are nonspecific and can mimic those of other conditions. EMP of the nasopharynx presents as a slow-growing, radiosensitive mass with a favorable prognosis. We present the case of a 55-year-old male patient who sought medical attention for recurrent epistaxis. An endoscopic examination revealed a tumor located in the nasopharynx, which was confirmed by MRI as a confined nasopharyngeal mass. Subsequent pathology studies, laboratory results, and bone marrow biopsy were consistent with a solitary EMP of the nasopharynx.

Primary hepatic leiomyosarcoma with adrenal and hepatic metastasis: Case report and literature review.

Primary hepatic leiomyosarcoma (PHL) is a rare malignant tumor, which originates from smooth muscles. The imaging features are nonspecific and the diagnosis is often delayed until the tumor reaches a large size, which leads often to a dismal prognosis. We report a case of a 46-year-old male patient who was complaining about abdominal pain for 2 months. The imaging revealed the presence of a large mass in the liver with adrenal and liver metastasis. Diagnosis of PHL was confirmed by histopathological and immunohistochemical examinations. In this case report, we review the epidemiological, clinical, and paraclinical aspects of the disease, as well as the treatment modalities.

A rare cause of hemoptysis: Primitive pulmonary synovial sarcoma.

Synovialosarcoma is a mesenchymal tumor with soft tissue predilection, metastasizing to various organs, including the lung. Primary pulmonary involvement is rare and requires histological examination for confirmation. In early stages, the treatment is surgical followed by radiotherapy to avoid recurrence, while there's no consensus in chemotherapy. We present a case of a 54-year-old patient with primary pulmonary synovialosarcoma. The patient underwent successful treatment, achieving tumor control and complete excision. This case discusses diagnostic approaches, prognosis, treatment modalities for primary pulmonary synovialosarcoma, emphasizing the significance of early intervention for favourable outcomes.

Breast adenomyoepithelioma diagnosed on core needle biopsy: a diagnostic challenge.

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.

Primary cutaneous adenoid cystic carcinoma with lung metastasis: A case report with literature review.

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.

Primary rectal adenocarcinoma with musculoskeletal metastasis as the only metastasis site: A case report with a short literature review.

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.

Hepatic hydatid cyst fistulized in the duodenum: Extremely rare complication.

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.
