Uncommon orbital metastasis in ductal breast carcinoma: a rare presentation 12 years after treatment.

Orbital metastasis originating from breast carcinoma, particularly ductal carcinoma, represents a rare clinical entity, with lobular carcinoma usually being more common. Long-term surveillance in breast cancer patients is crucial for early detection of metastasis. Herein, we present a case of a 70-year-old woman with a history of left ductal breast carcinoma, diagnosed and treated 12 years ago. She then developed left eye vision loss, diplopia, enophthalmos, and chemosis in October 2024. Imaging revealed orbital metastasis involving the left superior and lateral rectus extraocular muscles. Biopsy confirmed the diagnosis of orbital metastases arising from ductal breast carcinoma. This case underscores the significance of long-term surveillance in breast cancer patients, as metastasis can manifest years after the initial diagnosis. Despite its rarity, orbital metastasis warrants consideration in the differential diagnosis of ocular symptoms in patients with a history of breast carcinoma. Treatment primarily aims at palliation and preserving visual function, with prognosis typically poor.

Bilateral swelling of the lacrimal glands as first manifestation of systemic sarcoidosis in a patient with breast cancer.

Sarcoidosis, a multifaceted granulomatous disease primarily affecting the lungs, occasionally presents in atypical locations. Lacrimal gland involvement, though rare, poses distinct diagnostic challenges. This case report details a 52-year-old female with bilateral lacrimal gland swelling initially suggestive of metastatic tumor due to a history of breast cancer. Subsequent investigations, including CT and MRI, unveiled pulmonary sarcoidosis. Discussion emphasizes the diverse ocular manifestations of sarcoidosis, with lacrimal gland participation potentially indicating early stages. Diagnostic complexities involve differentiation from other lacrimal pathologies, including neoplasms, lymphoproliferative disorders, Sjögren's syndrome, Wegener's granulomatosis, tuberculosis, and IgG4-related disease. In summary, while lacrimal gland involvement in sarcoidosis is infrequent, it should be considered in orbital masses, necessitating a comprehensive approach for accurate diagnostic orientation in such cases.

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.

A rare case of anterior sternal metastasis in ovarian cancer: A case report.

A subcutaneous mass in the anterior region of the thorax, (presternal region). Subcutaneous metastases in ovarian cancer are rare, occurring in 0.9% to 5.8% of cases. They are usually a late manifestation that arises several years after the initial diagnosis and often serve as a poor prognostic indicator. Their presence suggests a reported median survival ranging from 3 to 18 months. subcutaneous metastases can be categorized into umbilical metastases, commonly referred to as Sister Joseph's nodules (SJN) the most prevalent type, and non-SJN cutaneous metastases. We present the unusual case of a 57-year-old woman who underwent surgical intervention and received adjuvant chemotherapy for serous ovarian adenocarcinoma. She presented for consultation 5 years later with a painful presternal mass, and the histopathological examination of the mass revealed a metastasis of the primary ovarian tumor.

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.

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.

Primary malignant melanoma of the parotid gland: A case report.

The primary malignant melanoma of the parotid is a rare and complex clinical entity, posing numerous diagnostic challenges due to the absence of melanin in the tumor and its histological similarities with other poorly differentiated lesions. Accurate diagnosis often requires advanced imaging techniques and immunohistochemical procedures to identify specific melanoma markers. Therapeutically, total parotidectomy with simultaneous cervical dissection is frequently recommended, although approaches combining surgery, chemotherapy, radiotherapy, or even immunotherapy are also being explored. Despite these advancements, malignant parotid melanoma continues to be associated with a grim prognosis, emphasizing the importance of ongoing research to improve therapeutic options and understanding of this rare pathology.

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.

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.

Bitemporal Lobe Cysts.

Teaching Point: Cystic brain necrosis is a rare but severe post-radiation complication; the late post-radiation context, the temporal location, and the MRI features can suggest the diagnosis.

Acquired cystic lymphangioma imitating breast cancer recurrence.

Cystic lymphangioma is a benign, congenital lymphatic malformation mainly encountered in infants during the first 2 years of life. It is rarely found in adults. Cystic lymphangioma of the breast is an extremely uncommon entity, and only a few cases have been described in the literature. We present the case of a 52-year-old female who had a mastectomy and chemoradiotherapy for breast cancer 8 years ago and in whom we discovered a suspicious mass of the treated breast through an annual imaging check-up. A cancer recurrence was suspected, and the patient underwent surgical resection. Pathology results were consistent with a cystic lymphangioma.

Synchronous bilateral breast cancer: A first case with lobular and mucinous carcinoma.

This report describes a rare case of synchronous bilateral carcinoma of the breast in a postmenopausal female patient, with mucinous carcinoma measuring 5 cm in the left breast and multifocal multicentric lobular carcinoma in the right breast. The patient underwent a bilateral mastectomy with adjuvant chemotherapy. To the best of our knowledge, this is the first report of a case of mucinous carcinoma and infiltrating lobular carcinoma coexisting in distinct breasts.

Omental infarction found incidentally during metastatic workup: A report of 2 cases.

Omental infarction is an uncommon cause of acute abdominal pain that can occur in different several locations. We report 2 cases of omental infarction diagnosed at computed tomography (CT) scan performed as part of routine oncological surveillance, one right-sided and the other left sided. This paper illustrates the range of CT scan findings and highlights the important clinical implications of this radiological diagnosis.

Chest wall bone late recurrence of an endometrial adenocarcinoma.

Among gynecological malignancies, Endometrial cancer stands out as the most prevalent form of carcinoma. However, Adenocarcinoma is the most frequent histological type of Endometrial cancer. Endometrial metastases are generally confined to pelvis, and distant metastases are seen primarily in the lymph nodes, lungs, or liver. bone Endometrial metastases are detected from 2% to 6% at diagnosis. Bones metastasis are generally restricted to the pelvis, vertebrae, and femur. Other locations such as the peripheral skeletal, chest wall, cranium and bone recurrence later after initial treatment are very unusual. In cases of bone recurrence, adenocarcinoma is the most seen. CT and PET/CT scan are the most useful diagnostic modality for the detection of a bone metastasis. Here, we report a chest wall bone late recurrence of an endometrial adenocarcinoma.

Male breast myofibroblastoma: Imaging features and ultrasound-guided core biopsy diagnosis.

Mammary myofibroblastoma is a rare mesenchymal neoplasm that typically presents in older men and women. Less commonly, these benign tumors may also occur in soft tissues located outside of the breast, in which case they are referred to as mammary-type myofibroblastomas. The histologic composition of this benign spindle cell tumor can be markedly varied. We present one such case of myofibroblastoma of the male breast, describing its sonographic appearance and its diagnosis using ultrasound-guided core biopsy.

An unusual cause of peritonitis: Perforation of a gastric carcinoma.

Gastric carcinoma perforation is an uncommon consequence that is often missed during the preoperative stage. Perforation may occur at any stage of cancer, but it is more common in late stages. It can also happen early in the illness. Because of the spilled stomach contents, it produces an acute abdominal syndrome. The goal of treatment should be to strike a balance between the emergency situation of peritonitis and oncological surgical techniques. A case of stomach cancer perforation with typical imaging findings is presented.

An etiology of ground - glass images during COVID-19: Pneumocystis jiroveci pneumonia.

Pneumocystis jiroveci pneumonia is a common pathology in HIV-infected but also in uninfected immunocompromised individuals. The pandemic coronavirus disease 2019 (COVID-2019) is a new type of coronavirus disease caused by SARS-COV-2, and the chest imaging is often used as complementary tool in patients' evaluation. The imaging finding is similar with many pulmonary pathologies. Chest computed tomography scan is gold standard imaging and shows a central and diffuse distribution, ground- glass pattern with septal thickening with "crazy paving pattern." We reported a case of 57-year-old man patient, followed in oncology for laryngeal cancer who presented of Pneumocystis jiroveci pneumonia during his follow-up. The diagnosis is confirmed by polymerase chain reaction with bronchoalveolar lavage fluid. Other immunochemical tests can be performed but are less specific. Both curative and preventive treatment in subjects at risk remains trimethoprim-sulfamethoxazole. Corticosteroid therapy may be associated depending on the case.

Not to be confused, this is a pleural fibroma: Case report and literature review.

Solitary fibrous tumors of the pleura are rare mesenchymal tumors. The diagnosis is often made incidentally. We report the case of 65 year old patient consulting for dry cough evolving for 1 year. The clinical examination revealed a mattness of the right hemi thorax. The chest X-ray detected a right lower lobar opacity. The CT scan showed a right lateral basal mass, connected at an obtuse angle with the wall. A CTguided biopsy with an anatomopathological and immunohistochemical examination were performed, thus confirming the diagnosis of a solitary fibrous pleural tumor. The evolution after treatment was favorable. Complete surgical resection of the tumor is usually sufficient, but there are reported cases with recurrence.
