A case of pancreatic duct cell carcinoma with ossification was reported. A 71-year-old female died of pancreas carcinoma with liver and diffuse lymph node metastasis. Computed tomography (CT) revealed a punctate calcification of the body of the pancreas. At autopsy, the carcinoma occupied almost all of the pancreas, and histological examination revealed a moderately to well-differentiated adenocarcinoma with mucin production in the glands. The whole of the pancreas was examined microscopically by multiple-step sections, and mature ossification was found in the body, corresponding to its CT localization. Around the ossification were found cancer cells with massive mucin in the cytoplasm, capillary proliferation, scattered necrosis and mesenchymal cells, which were thought to be fibroblasts. But neither cartilage nor calcification was found. The pathogenesis of ossification was believed to be associated with metaplastic changes of mesenchymal cells. This is the fourth case of pancreatic carcinoma with ossification, and the second case of pancreatic duct cell carcinoma with mature bone formation to have been reported.

We report a rare case of secondary involvement of the gallbladder by metastatic renal cell carcinoma. A 71-year-old man was diagnosed as having a polypoid mass within the gallbladder when he underwent right nephrectomy for a renal cell carcinoma. A preoperative diagnosis of simultaneous carcinoma of the gallbladder was made, and extended cholecystectomy with regional lymphadenectomy was performed five months after the initial operation. Postoperative histological examination of the polypoid mass within the gallbladder and a pancreatic mass excised during the second surgery revealed these resected tumors to be identical to the clear cell type of renal cell carcinoma. We feel that this case presents synchronous involvement of the gallbladder and pancreas by metastatic renal cell carcinoma of the right kidney.

A 71-year-old Japanese man with basaloid-squamous carcinoma of the esophagus is reported. The carcinoma contained basaloid cells, a few small cornified foci, and a large amount of eosinophilic hyaline substance, which reacted positively upon periodic acid-Schiff, type IV collagen, and laminin staining. Ultrastructural examination revealed markedly replicated basement membranes (BM). The morphological findings suggested that this tumor secreted abundant BM substance. Small nests of cancer cells were attached to the dysplastic esophageal epithelium. The tumor cells exhibited negative staining for mucin, secretory component, lactoferrin, and carcinoembryonic antigen. These findings, as well as the observed keratinization and attachment between the carcinoma nests and mucosal epithelium, indicate that the tumor originated in the mucosal epithelium of the esophagus.

A 71-year-old man developed metastatic cutaneous nodules of colon carcinoma on the scalp and chest wall. Histopathological findings revealed aggressive invasion of the tumor cells into the overlying epidermis (epidermotropic carcinoma); they occasionally adhered to the epidermal cells. These morphological features have not been described in cutaneous metastases from internal carcinomas.

A 71-year-old man with a penile verrucous carcinoma presenting as a large cutaneous horn is described. Both verrucous carcinoma and penile cutaneous horn are relatively uncommon entities and have not been previously reported to occur concomitantly. A brief review of the relevant medical literature and methods of therapy is included.

A 71-yr-old woman with a widely metastatic lipid-rich variant of breast cancer was found to have striking hyperamylasemia (85-fold normal). By isoelectric focusing, agarose gel electrophoresis, and a wheat protein inhibitor assay, the predominant serum amylase appeared to be identical to pancreatic isoamylase. Serum trypsin, serum lipase, and an abdominal computed tomography scan were normal, excluding the possibility of pancreatitis. Furthermore, both the primary breast tumor and skin metastases that developed 10 yr later stained immunohistochemically for amylase. Thus, breast carcinoma must be added to the list of tumors causing ectopic hyperamylasemia, and this case shows that nonpancreatic malignancies may produce pancreatic-type hyperamylasemia.

A 71-year-old man was admitted with the chief complaint of gross hematuria. Cystoscopic examination showed a broadbased papillary tumor at the apex of the bladder. There was edema of the mucous membrane around the tumor. CT-scan demonstrated a mass extending from the bladder dome superiorly. Partial resection of the bladder was done. Pathological examination revealed grade 3 transitional cell carcinoma, with scattered adenocarcinoma and squamous cell carcinoma foci. Chemotherapy with bleomycin (BLM) and cis-dichlorodiamine platinum (CDDP) was done postoperatively. Ten months after the operation, he was readmitted because of recurrence in retroperitoneal lymph nodes. Chemotherapy with BLM and CDDP was done, but he died of pulmonary complications. Autopsy revealed retroperitoneal lymph node metastasis of transitional cell carcinoma. There was no metastasis to any other organ. We briefly discuss 275 cases of the carcinoma of the urachus collected from the Japanese literature.

A case of advanced gastric cancer associated with metastatic carcinomatosis of the bone marrow, microangiopathic hemolytic anemia (MAHA) and disseminated intravascular coagulation (DIC) was reported. A 71-year-old woman complained of lumbago and general fatigue. At the time of admission, besides anemia, jaundice and a tendency to bleeding, the laboratory data showed, hyperbilirubinemia, elevated FDP and hemolytic anemia with fragmented red cells. The bone marrow was infiltrated by carcinoma, and an upper GI series examination showed Borrmann II type gastric cancer on the greater curvature of the antrum. After remission of both MAHA and DIC by mitomycin C, neothramycin and FOY, the patient successfully underwent subtotal gastrectomy. However, she died of cerebral hemorrhage on the 96th postoperative day.

A 71-year-old female presented with a midline neck mass. The clinical impression was that of a thyroglossal cyst but preoperative assessment suggested a solid lesion, possibly malignant. The mass was removed surgically using the Sistrunk technique and shown pathologically to be a mixed papillary-follicular carcinoma of the thyroid with no cystic elements. Clinically and radiologically the thyroid was normal and thyroidectomy was not performed. This management is discussed along with a brief review of the relevant literature on the pathology and treatment of similar lesions.

A 71-year-old man developed severe hemorrhagic proctitis 1 year after pelvic irradiation for carcinoma of the urinary bladder. Conservative treatment as well as performance of a colostomy failed to control the rectal bleeding. After irrigation of the rectum with a formalin solution the bleeding stopped, and no recurrence has been observed for the next 14 months.

PMID:Formalin treatment of radiation-induced hemorrhagic proctitis. 348 6
