Diagnosing Primary Malignancy in Leptomeningeal Carcinomatosis by Using CSF Cytology and Immunohistochemistry: A Case Report

We present a rare case of recurrent carcinoma of gallbladder with leptomeningeal carcinomatosis. Cerebrospinal fluid (CSF) cytology showed atypical cells, which were suspicious for malignancy on initial reporting. Diagnosis of malignancy and primary from hepatobiliary source was confirmed by doing immunohistochemistry on CSF cell block.

Breast metastasis from recurrent gallbladder adenocarcinoma: a case report with review of the literature

Gallbladder adenocarcinoma has a poor prognostic. The leading modes of dissemination in gallbladder cancer (GBC) are lymphatic, vascular, neural, intraperitoneal, and intraductal. The most common site of dissemination is liver. Breast metastasis in GBC is an unusual site of dissemination. Only few cases have been reported in the literature. We report a rare case of solitary breast metastasis from recurrent gallbladder carcinoma in light of existing literature.

Skeletal metastasis in gallbladder cancer from a high-volume tertiary care center of north India: a series of rare occurrence

PURPOSE

Gallbladder carcinoma is usually characterized by late diagnosis and poor prognosis. Skeletal metastases in gallbladder cancer have been rarely reported in literature. In this study, we evaluated the incidence of skeletal metastasis in gallbladder cancer at our high-volume center and their clinical presentation, radiological imaging, treatment received, outcome, and survival.

METHODS

Records of all gallbladder carcinoma patients registered in our department from October 2007-October 2012 were retrospectively reviewed to identify gallbladder cancer patients with skeletal metastasis and their data was collected and analyzed.

RESULTS

Out of 340 cases of gallbladder carcinoma, 189 (55.58 %) were having stage IV disease. Of these, seven (2.1 %) patients had cytologically proven skeletal metastasis. All seven patients had advanced loco-regional abdominal disease with coexistent liver metastasis. Presenting symptoms were predominantly weight loss and back pain with markedly elevated serum alkaline phosphatase (median = 1231 IU/ml). Dorsolumbar vertebral metastasis was the most common site of skeletal metastasis in our series (5/7), followed by pelvic bone (2/7) while skull and sternal metastasis were present in one patient each. All these patients had short median survival (median = 30 days, range = 15-60 days).

CONCLUSIONS

Incidence of skeletal metastasis in gallbladder cancer is very low (2.1 %). Axial skeleton was the most common site of bone metastasis. Gallbladder cancer with skeletal metastasis portends poor prognosis with rapidly fatal course.

Leptomeningeal dissemination in gall bladder carcinoma: sequelae of long-term survival?

Patients with gall bladder malignancies usually present at an advanced stage with less than 20% cases being resectable at presentation and over a half harbouring distant metastases to liver or paraaortic nodes. Long-term cure is uncommon and so is the presence of central nervous system metastases. We present the case of a middle-aged woman with adenocarcinoma gall bladder, treated with postoperative locoregional irradiation following simple cholecystectomy, who developed headache, backache, vision loss, and multiple joint pains six years following adjuvant therapy. A diagnosis of leptomeningeal carcinomatous meningitis was established with cerebrospinal fluid cytology positivity for carcinoma. She deteriorated on palliative cranial irradiation and was managed with best supportive care.

Solitary breast metastasis from recurrent gallbladder carcinoma simulating a second primary on 18F-FDG PET/CT

Gallbladder carcinoma is characterized by poor prognosis. It spreads by direct, lymphatic, vascular, neural, intraperitoneal, and intraductal routes. The most commonly involved organ is the liver followed by regional lymph nodes. Extra-abdominal metastases are comparatively rare. We present a case of solitary breast metastasis from recurrent gallbladder carcinoma mimicking a primary breast cancer in (18)F-FDG PET/CT.

Gastrointestinal cancer and brain metastasis: a rare and ominous sign

Metastatic brain tumors represent 20% to 40% of all intracranial neoplasms and are found most frequently in association with lung cancer (50%) and breast cancer (12%). Although brain metastases occur in <4% of all tumors of the gastrointestinal (GI) tract, the incidence of GI brain metastasis is rising in part due to more effective systemic treatments and prolonged survival of patients with GI cancer. Data were collected from 25 studies (11 colorectal, 7 esophageal, 2 gastric, 1 pancreatic, 1 intestinal, 3 all-inclusive GI tract cancer) and 13 case reports (4 pancreatic, 4 gallbladder, and 5 small bowel cancer). Brain metastases are found in 1% of colorectal cancer, 1.2% of esophageal cancer, 0.62% of gastric cancer, and 0.33% of pancreatic cancer cases. Surgical resection with whole brain radiation therapy (WBRT) has been associated with the longest median survival (38.4-262 weeks) compared with surgery alone (16.4-70.8 weeks), stereotactic radiosurgery (20-38 weeks), WBRT alone (7.2-16 weeks), or steroids (4-7 weeks). Survival in patients with brain metastasis from GI cancer was found to be diminished compared with metastases arising from the breast, lung, or kidney. Prolonged survival and improvement in clinical symptoms has been found to be best achieved with surgical resection and WBRT. Although early treatment has been linked to prolonged survival and improved quality of life, brain metastases represent a late manifestation of GI cancers and remain an ominous sign.

Bone metastases as the initial presentation of carcinoma of gall bladder: a rarity

Distant metastases are rare form of presentation of carcinoma gall bladder. Bony pain as initial presentation is quite unusual. A 50-year-old woman presented with the pain in right shoulder. Investigation showed metastatic adenocarcinoma in the head of humerus and the primary was found in the gall bladder. She received local radiotherapy for bone metastases and undergoing systemic chemotherapy. Carcinoma gall bladder is a common abdominal malignancy, mostly presenting in advanced stage with abdominal symptoms and obstructive jaundice. In presence of metastasis, the management is palliative and role of chemotherapy is limited for palliation symptoms.

Intracranial metastasis or meningioma? An uncommon clinical diagnostic dilemma

BACKGROUND

Cerebral metastases are the most frequent brain tumors in adults and they may occasionally present as an isolated meningeal mass, suggesting a meningioma. Because of the prognostic relevance in discriminating both tumors, we review the literature and analyze four patients in whom the diagnosis of meningioma was initially made.

CASE DESCRIPTION

Four cases of isolated meningeal metastases are presented and in all of them a meningioma was considered as the main preoperative diagnosis. Only one patient had a history of previous cancer. The primary tumors found after pathological testing of the lesions were thyroid carcinoma, prostate adenocarcinoma, breast adenocarcinoma, and hypernephroma. The clinical and neuroimaging features as well as the differential diagnoses are discussed. The literature regarding these forms of meningeal metastases was reviewed.

CONCLUSIONS

Although they are uncommon, dural metastases can be mistaken for meningiomas. Our experience in these cases has led us to consider ordinary metastases as a differential diagnosis even when a meningioma is suspected. The definitive diagnosis of a meningioma should be established only after the histopathological report has been analyzed.

Case report. Orbital metastasis from gall bladder carcinoma

Clinical presentation of an extraabdominal metastasis from carcinoma of the gall bladder is rare. Orbital metastasis from gall bladder carcinoma has not been previously reported. We report a case of a 40-year-old woman who developed orbital metastasis from carcinoma of the gall bladder.
