Esophageal post‐Therapy Myeloid Sarcoma masquerading as Poorly Differentiated Adenocarcinoma: A Diagnostic Pitfall

Poorly Differentiated ◽

The Right

Metastatic tumours of the hand are uncommon. The majority of these tumours affect the phalanges and the primary tumours are usually bronchogenic in origin, with breast and kidney tumours next in frequency. Metastatic gastrointestinal to the hand is rare and usually from the colon. We report a case of poorly differentiated adenocarcinoma of the stomach antrum presenting with a metastatic lesion to the right 4th metacarpal bone. A review of the literature is included.

Unusual Appearance

A 60 year old man was referred to our hospital with the chief complaints of abdominal pain and vomiting. He underwent a distal gastrectomy with a Billroth II gastrojejunostomy for a peptic ulcer 13 years ago. Esophagogastroduodenoscopy (EGD) did not reveal any gross lesion in the stomach but depigmented areas were seen in the anastomosis line. The histopathology of the anastomotic area revealed poorly differentiated adenocarcinoma. Gastric stump cancers can be polypoid, fungating, ulcerated and diffusely infiltrating tumors respectively. In our case, the appearance of adenocarcinoma was quite different from that described in the classification system.

Detailed Review ◽

Aim: To identify the rate of incidental prostate cancer in patients undergone Transurethral resection of prostate(TURP) over a period of 5 years in our center. Methods: A Retrospective review was conducted using Histopathological department database on all TURP specimens over a period of 5 years from January 2015 to December 2019. Results: Out of 570 cases of TURP during our study period, 1.9% had incidental prostate cancer. Most of these positive cases had a Gleasons score of 10, which represent poorly differentiated Adenocarcinoma. Conclusion: The value of pathologic review of TURP specimens is limited but a detailed review helps to reduce under detection of prostate cancer.

Abstract We describe a Paneth cell carcinoma arising within the ampulla of Vater in a 64-year-old man. The phenotype of virtually all neoplastic cells was consistent with that of Paneth cells, based on routine morphology and their strong positive immunostaining for lysozyme. Additional widespread positive immunostaining for carcinoembryonic antigen and CA 19.9 supports a totipotential cell as the origin of such neoplastic cells. This case, therefore, represents a true Paneth cell carcinoma, as opposed to inclusion of occasional neoplastic Paneth cells into a poorly differentiated adenocarcinoma. This pattern of differentiation is rare, and predictions regarding its ultimate biological behavior and malignant potential must be guarded.

Gastric Choriocarcinoma

Abstract Choriocarcinoma is a rapidly invasive, widely metastatic human chorionic gonadotropin (HCG)–producing neoplasm, usually intrauterine and gestational. Primary gastric choriocarcinoma is very rare, and its pathogenesis is still uncertain. We report a case of primary gastric choriocarcinoma associated with adenocarcinoma in a 36-year-old woman. The patient presented with gastrointestinal bleeding and a gastric mass clinically suspicious of gastric adenocarcinoma. Histopathologic evaluation proved the tumor to be a choriocarcinoma, with a minor component of a poorly differentiated adenocarcinoma. The patient was treated with a standard nongestational choriocarcinoma chemotherapy regimen. An impressive initial response was evidenced by clinical reduction of the tumor volume and drop of the serum β-HCG levels after the first cycle. However, the tumor rapidly recurred in the abdomen and disseminated to the lungs, which were documented by new elevation of serum β-HCG levels and computed tomographic scans despite continuing with 3 more cycles of chemotherapy. The patient died 6 months after diagnosis.
