BACKGROUND: Triplet chemotherapy, with docetaxel-5FU-oxaliplatin (TEFOX), has yielded promising results in patients with advanced and operable gastric adenocarcinoma. This may prove useful in treating signet ring cell carcinoma (SRCC), which is known to be chemoresistant and has a poor prognosis. We therefore evaluated TEFOX in patients with untreated advanced SRCC. METHODS: Patients with metastatic or locally advanced non-resectable SRCC were treated with TEFOX...

Invasive carcinoma of no special type (NST) or ductal carcinoma is the largest group of invasive breast cancers. Invasive lobular carcinoma (ILC) is the second most common histological type; it comprises 5%-15% of all invasive breast cancers. Historically, lobular neoplasia and invasive lobular carcinoma may produce intracellular mucin that pushes the nucleus to one side, creating the characteristic signet ring cell morphology. The extracellular mucin secretion is essentially described in mucinous breast carcinoma...

Signet ring cell carcinoma (SRCC) of the ampulla of Vater is an extremely rare tumor. Our case describes a 45-year-old female presenting with jaundice and pruritus. Computed tomography, endoscopy, and endoscopic retrograde cholangiopancreatography showed a tumor of the ampulla of Vater without distant metastasis. Histological biopsy confirmed a malignant tumor with SRCC characteristics and immunohistochemical staining revealed a mixed type profile (both intestinal and pancreatobiliary characteristics). A pylorus-preserving pancreatoduodenectomy was performed and the patient recovered without complications...

Signet ring cell carcinoma, a subtype of adenocarcinoma, is a rare cause of primary lung cancer. The authors report a case of primary lung signet ring cell carcinoma presenting as a cavitary Pancoast tumor in a 32-year-old male smoker. Beyond the rarity of primary lung signet ring cell carcinoma itself, the youth of the patient, his smoking status, the presence of cavitation, and the location of the tumor in the superior sulcus make it especially atypical.

Background: Chronic idiopathic inflammatory bowel disease (IBD) is a significant risk factor for the development of intestinal adenocarcinoma. The underlying molecular alterations in IBD-associated intestinal adenocarcinoma remain largely unknown. Methods: We compared the clinicopathologic and molecular features of 35 patients with 47 IBD-associated intestinal adenocarcinomas with a consecutive series of 451 patients with sporadic colorectal carcinoma identified at our institution and published data on sporadic colorectal carcinoma...

Signet-ring cell carcinoma (SRCC) is an adenocarcinoma characterized by mucin-producing cells and most commonly arises in the stomach. Colonic SRCC can share features of colitis, including long segments of concentric bowel wall thickening and ulcerated mucosa with regions of sparing. We describe a rare case of metastatic gastric SRCC mimicking Crohn's disease. Our patient underwent 2 colonoscopies, and biopsies revealed chronic active inflammation with no evidence of malignancy. The diagnosis of SRCC was only made after colectomy was performed for recurrent bowel obstruction...

RATIONALE: With the increasing survival rate of gastric cancer, more multiple primary cancers (MPC) have been reported. However, few cases involve metachronous multiple primary cancers which both occurred in the stomach. PATIENT CONCERNS: An 83-year-old Chinese male had been diagnosed with gastric cardia cancer and underwent proximal gastrectomy. The pathological result was gastric adenocarcinoma. 13 years later the patient's gastroscope result deteriorated. The biopsy of the antrum revealed dysplasia with doubtful focal cancerization...

A 53-yr-old woman who presented with elevated renal indices was discovered to have a 4.5 cm right renal mass and an incidental 9.7 cm left ovarian mass on imaging studies. She underwent a partial nephrectomy and bilateral salpingo-oophorectomy, revealing a chromophobe renal cell carcinoma and an unusual ovarian neoplasm with epithelioid cells displaying prominent signet ring cell-like morphology. Immunohistochemical analysis of the ovarian neoplasm demonstrated that the tumor cells were diffusely immunoreactive for smooth muscle markers and negative for all tested cytokeratins and epithelial membrane antigen...

BACKGROUND: Signet-ring cell carcinoma (SRCC) is a very rare subtype of colorectal adenocarcinoma (COAD) with a poor clinical prognosis. Although understanding key mechanisms of tumor progression in SRCCs is critical for precise treatment, a comprehensive view of genomic alterations is lacking. MATERIALS AND METHODS: We performed whole-exome sequencing of tumors and matched normal blood as well as RNA sequencing of tumors and matched normal colonic tissues from five patients with SRCC...

REVIEW
Mustafa Mohammad, Rebecca Wilcox
Acantholytic squamous cell carcinoma (acantholytic SCC) is a variant of SCC in which acantholysis develops owing to the loss of desmosomal adhesion proteins. This loss of cell-cell adhesion leads to morphologic changes that have the potential to mimic other tumor types, such as angiosarcoma or signet ring cell adenocarcinoma. Acantholytic SCC characteristically occurs in sun-exposed skin of elderly patients; however, it can occur in nondermal locations. We present a review of the literature describing cases of nondermal acantholytic SCC...

Situs inversus totalis (SIT) is a congenital anomaly characterized by a complete mirror-image transposition of the thoracic and abdominal viscera. We report on a rare case of superficial spreading gastric cancer associated with SIT in a 66-year-old woman referred to our hospital for examination of gastric cancer initially diagnosed by medical check-up. Esophagogastroduodenoscopy showed a slightly depressed lesion in the lesser curvature side of the stomach. Abdominal contrast-enhanced computed tomography showed complete transposition of the abdominal viscera, confirming SIT...

INTRODUCTION: In developed countries, authors have reported variations over time in the seat and histological type of gastric adenocarcinomas, which were explained by Helicobacter pylori infection (HPI) incidence changes. In North-African countries and the Arabic world, epidemiological changes in gastric adenocarcinomas are still unknown. Our study aims to explore and to describe those changes in central Tunisia. MATERIALS AND METHODS: This is a retrospective observational and descriptive study including 876 cases based on the National Central Tunisian Register of Cancers over a period of 21 years...

Zhiming Yang, Jonathan I Epstein
Urothelial carcinoma in situ (CIS) of the bladder with glandular differentiation (CIS-GL) is rare with some showing an association with small cell carcinoma. There is a paucity of data on whether CIS-GL diagnosed in the absence of invasive carcinoma is associated with an increased risk of developing small cell carcinoma of the bladder. Twenty-seven cases of CIS-GL were identified from the consult files of one of the authors from 2008 to 2015 without prior or coexisting invasive carcinoma at the time of diagnosis...

Mucinous carcinoma of the breast represents 1%-4% of all breast cancers. The World Health Organization classification divides this type of tumour into three different subtypes: mucinous carcinoma, mucinous carcinoma with tall columnar cells (mucinous cystadenocarcinoma and columnar cell mucinous carcinoma) and signet ring cell carcinoma. A 74-year-old woman presented a tumour with inflammatory features in the upper outer quadrant of her left breast, 7 cm in diameter. The core biopsy showed infiltrating ductal carcinoma of no specific type...

A 65-year-old man underwent subtotal gastrectomy for advanced gastric cancer. The histological type of the cancer was signet-ring cell carcinoma, and the clinical stage was stage IB (T2N0M0). Three years after surgery, the patient had the following symptoms:dysphagia, odynophagia, and weight loss. Esophageal endoscopy and esophagography revealed a circular stenosis covered with the normal mucosa between the middle esophagus and the esophagogastric junction. Histologically, the samples obtained by staging laparoscopy revealed signet-ring cell carcinoma...

In the World Health Organization (WHO) classification, adenocarcinoma of esophagus comprises preinvasive type (dysplasia), adenocarcinoma, adenoid cystic carcinoma, adenosquamous carcinoma, and mucoepidermoid carcinoma. For adenocarcinoma, it is important to determine the grading of the cancer and histological variants such as signet ring adenocarcinoma. In the current day management of esophageal adenocarcinoma by neoadjuvant therapy, the histology of the cancer and the lymph nodal status may change after the therapy...
