Isolated pancreatic metastasis from uterine cervical cancer: a case report

Successful radiotherapy for recurrent obstructive pancreatitis secondary to pancreatic metastasis from cervical squamous-cell carcinoma

Metastatic pancreatic cancer is a rare condition and cases of pancreatic metastasis from cervical cancer are infrequently reported. Furthermore, the incidence rates of pancreatic tumors as the cause of pancreatitis and of pancreatitis in patients with pancreatic tumors are similarly low. Pancreatitis may occur when a tumor obstructs the pancreatic duct. This condition may be difficult to manage and significantly reduces the quality of life because of severe abdominal pain. Here, we present a rare case of obstructive pancreatitis caused by pancreatic metastasis from cervical squamous-cell carcinoma, pathologically confirmed using endoscopic ultrasonography-guided fine-needle biopsy and treated with palliative irradiation to achieve rapid therapeutic relief. It is important to obtain appropriate tissue samples, confirm the pathological diagnosis, and compare the pathological findings with those of the primary tumor to select the appropriate treatment for obstructive pancreatitis caused by a metastatic pancreatic tumor.

A case report of carcinoma of uterine cervix throwing heterochronous metastasis to the skin, spleen, and pancreas: the role of multimodality treatment approach

BACKGROUND

Cancer of cervix often fails locally and/or within the pelvis. One to two percent of cervical squamous cell carcinoma patients have lung metastases at presentation, and 5-35% develop pulmonary metastases later on. Common sites of metastases are the liver, bone, and bowel. We report a rare case presentation of cervical squamous cell cancer where heterochronous metastasis occurred in the skin, spleen, and pancreas without loco-regional recurrence and skipping of visceral organs such as the lung, liver, and brain.

CASE PRESENTATION

A 55-year-old, postmenopausal lady presented with a complaint of bleeding of the vagina for 2 months duration. Cervical biopsy revealed squamous cell carcinoma of the cervix, and she was staged as a case of FIGO stage IIIB. She received external beam-beam radiotherapy of 50 Gy in 25 fractions along with concurrent weekly cisplatin at 35 mg/m² followed by 3 fractions of intracavitary brachytherapy of 6 Gy each. After 30 months of follow-up, she presented with a skin lesion of 6 × 5 cm² in the infrascapular region for 2 months duration. Biopsy revealed metastatic squamous cell carcinoma. Her metastatic work-up revealed no other lesions. Palliative radiotherapy to local site of 8 Gy in single fraction was delivered. The lesion disappeared within 4 weeks. She was given 6 cycles of cisplatin and paclitaxel salvage chemotherapy. After 30 months of follow-up, she presented with a skin lesion of 6 × 5 cm² in the infrascapular region. Biopsy revealed metastatic squamous cell carcinoma. Her metastatic work-up revealed no other lesions. Palliative radiotherapy to the local site was planned, and a dose of 8 Gy in a single fraction was delivered. The lesion disappeared within 4 weeks. She was given 6 cycles of cisplatin and paclitaxel salvage chemotherapy. Six months after the completion of salvage therapy, she reported with the complaints of recurrent bouts of hematemesis and melena. Her CECT scan revealed 2 × 1.5 cm² growth in the body of the pancreas and a subcentric splenic hilum node. She underwent open splenectomy with distal pancreatectomy. Histopathology report showed metastatic infiltration in pancreatic tissue by squamous cell carcinoma and one metastatic node in the splenic hilum. Post-treatment, 6 months, the patient was asymptomatic with no recurrence.

CONCLUSIONS

This is a rare heterochronous metastatic presentation of cervical cancer without loco-regional recurrence and visceral organs such as the lung, liver, and brain. The optimal treatment remains undefined for these patients. Multimodality treatment is necessary to manage the patients.

Pancreatic Metastasis from Adenocarcinoma of the Uterine Cervix

Pancreatic metastasis from cervical cancer is extremely rare. We report a case of metastatic adenocarcinoma of the pancreas from uterine cervical cancer. A 70-year-old woman was referred because of a pancreatic mass detected by CT. She had been diagnosed with uterine cervical adenocarcinoma 20 months previously. After concurrent chemoradiotherapy, CT showed no evidence of the cervical mass, and follow-up showed no evidence of recurrence. Endoscopic ultrasound-guided fine needle aspiration biopsy of the pancreatic mass resulted in a diagnosis of metastatic adenocarcinoma from uterine cervix.

Peri-Ampullary Metastasis From Endometrial Adenocarcinoma: A Rare Etiology of Obstructive Jaundice

Endometrial cancer is the commonest gynecologic malignancy, of which adenocarcinoma is the most common histologic type. While most women who relapse present with local symptoms within 3 years of the initial diagnosis, metastatic disease usually involves the abdominal cavity and liver. Herein we present a rare case of a patient with a remote history of endometrial adenocarcinoma status-post curative surgical resection and adjuvant therapy who presented with obstructive jaundice proved to be secondary to peri-ampullary metastasis of uterine adenocarcinoma.

Metastatic tonsillar squamous cell carcinoma masquerading as a pancreatic cystic tumor and diagnosed by EUS-guided FNA

Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA). This represents a third reported case of metastatic squamous cell carcinoma to the pancreas from the head and neck region. Metastatic squamous cell carcinoma should be considered in the differential diagnosis of EUS-FNA during evaluation of pancreatic cystic lesion.

Uterine cancer presenting as obstructive jaundice

Obstructive jaundice as an initial manifestation of uterine cancer is extremely rare. We present a case of a 72-year-old female who presented with obstructive jaundice, supposedly for pancreatic cancer. After detailed diagnostic investigation, the cause of the jaundice was attributed to a metastatic compression of the common bile duct, from the primary neoplasm of the uterus. This case highlights the importance of including uterine cancer in the differential diagnosis of woman presenting with obstructive jaundice, even though it is very rare.

Pancreatic metastasis from mixed adenoneuroendocrine carcinoma of the uterine cervix: a case report

Metastatic cancers of the pancreas are rare, accounting for approximately 2-4% of all pancreatic malignancies. Renal cell carcinoma is the most common solid tumor that metastasizes to the pancreas. Here, we present a case of uterine cervical carcinoma metastasizing to the pancreas and review the literature regarding this rare event. A 44-year-old woman with a uterine cervical tumor had undergone radical hysterectomy and had been diagnosed pathologically with stage Ib mixed adenoneuroendocrine carcinoma in 2004. She underwent concurrent radiotherapy and chemotherapy postoperatively. Pulmonary metastases subsequently appeared in 2008 and 2011, and she underwent complete resection of the lung tumors by video-assisted thoracic surgery. Although she was followed up without any treatment and with no other recurrences, positron emission tomography revealed an area of abnormal uptake within the pancreatic body in 2012. Enhanced computed tomography demonstrated a 20-mm lesion in the pancreatic body and upstream pancreatic duct dilatation. Endoscopic ultrasonography-guided fine needle aspiration was performed and pathological examination suggested neuroendocrine carcinoma (NEC). On the basis of these results and the patient's oncological background, lesions in the pancreatic body were diagnosed as secondary metastasis from the cervical carcinoma that had been treated 8 years earlier. No other distant metastases were visualized, and the patient subsequently underwent middle pancreatectomy. Pathological examination showed NEC consistent with pancreatic metastasis from the uterine cervical carcinoma. The patient has survived 7 months since the middle pancreatectomy without any signs of local recurrence or other metastatic lesions.
