Comparison of Encapsulated Versus Nonencapsulated 14C‐urea Breath Test for the Detection of Helicobacter pylori Infection: A Scintigraphy Study

14C‐urea breath test (14C‐UBT) is considered as “gold standard” for detection of active gastric H. pylori infection. However, till date no comparative study using encapsulated and non‐encapsulated 14C‐UBT protocols has been conducted in same subjects in identical conditions. We monitored gastric fate of capsule containing 14C‐urea with real time display and compared sensitivities of these protocols at different time points of breath collection.

Denovo malignant fibrous histiocytoma of breast: Report of a case and review of literature

Sarcomas are rare histological types of malignancy found in the breast. While angiosarcoma is the most common type of sarcoma found here, malignant fibrous histiocytoma (MFH) arising de novo is one of the rare varieties. We recently cared for a middle aged lady with a locally advanced fungating growth in her right breast. The patient underwent right modified radical mastectomy (MRM) as her fine needle aspiration cytology report was suggestive of malignancy. The histopathological report revealed the tumour to be MFH. The patient had an uneventful postoperative recovery and is subjected to adjuvant radiotherapy.

Squamous cell carcinoma arising in epidermal inclusion cyst of breast: A diagnostic dilemma

Epidermal, or inclusion, cysts are frequently seen benign lesions that are lined with stratified squamous epithelium. Malignant transformation of these is rare, occurring in 0.011% to 0.045% cases [1]. We herein report an unusual case of squamous cell carcinoma occurring in an epidermal cyst of the breast in a middle aged lady.

Primary neuroendocrine carcinoma breast: Our experience

OBJECTIVES This retrospective study was designed to present the clinical characteristics and histopathological features of Primary neuroendocrine carcinoma (PNEC) of breast, and to evaluate the impact on outcome following its management on the line of more common primary adenocarcinoma of breast. MATERIALS AND METHODS Records of four patients diagnosed with PNEC of breast were retrospectively reviewed. Data were obtained from medical record from January 2008 to December 2012. Diagnosis of PNEC was confirmed by histopathological examination (HPE) and immunohistochemical (IHC) staining of tissue obtained from Trucut biopsy of the breast lump in all four patients. PNEC of breast was defined by the presence of more than 50% of invasive tumor cells with cytoplasmic immunoreaction for neuroendocrine (NE) markers synaptophysin, chromogranin or neuron specific enolase as per WHO classification. All patients were treated with Modified Radical Mastectomy (MRM), six cycle of Cyclophosphamide, Adriamycin and 5-Flurouracil (CAF) based adjuvant chemotherapy, radiotherapy and hormonal therapy. RESULTS There were four female patients. The mean age was 58~years (50-65 years). Breast lump was the presenting complaint in all patients. The result of HPE showed tumor size ranging from 4 to 6.5 cm in diameter. Axillary lymph node metastasis was detected in three (75%) patients. ER and PR expression was positive in four (100%) and three patients (75%) respectively. None of the patients expressed Her-2-neu. IHC staining was positive for NE markers chromogranin in three (75%) patients, synoptophysin in two patients (50%) and Neuron specific enolase three (75%) patients. The mean follow-up time was 27.7 months (range 48-9). All four patients survived without any loco-regional or metastatic recurrence with one patient developing lymphedema of arm. CONCLUSIONS Breast lump is the most common presentation of PNEC of the breast with characteristic expression of NE markers by the tumor. Management of this rare tumor may include surgery, chemotherapy, radiotherapy and hormonal therapy depending on the size of the tumor, lymph node and hormone receptor status. However, most appropriate treatment plan has yet to be established.

Meckel’s diverticulum with benign stricture: A very rare cause of intestinal obstruction

We report a very rare case of Meckel’s diverticulum with benign stricture presenting as recurrent small bowel obstruction in a malnourished young adult female. Extensive preoperative investigations were unable to diagnose the cause of recurrent obstruction. Segmental small bowel resection with attached diverticulum was performed.

Clinico-epidemiological profile of breast cancer patients and the retrospective application of Gail model 2: An Indian perspective.

AIM To study the clinical and epidemiological profile of patients of breast cancer presenting at our center at New Delhi, India and to evaluate the applicability of Gail model 2 as a means of measuring 5-year and lifetime risk in our already diagnosed cases of breast cancer. METHODS This was a retrospective study conducted at Lady Hardinge Medical College Hospital in New Delhi, India, between January 2011 and July 2014. Two hundred and twenty two diagnosed cases of breast cancer were included. Information was collected retrospectively on a Performa from the medical record section and the Pathology department of the hospital.The predicted five-year and lifetime risk was calculated using GM2 prediction model from the NCIs breast cancer risk assessment tool website. RESULTS AND CONCLUSIONS Breast cancer in India is a far more biologically aggressive disease than in the west with a widely different spectrum of presentation and behavior and late presentation in an advanced stage. The accepted risk factors routinely associated with breast cancer in western literature do not appear to be relevant in the Indian population. Accepted western models do not seem to apply in the Indian scenario.

Short and hypertrophic ligament of treitz: a rare cause of superior mesentric artery syndrome.

Superior mesenteric artery syndrome (SMAS) is a rare form of upper intestinal obstruction in which the third part of the duodenum is compressed between the superior mesenteric artery and the aorta, secondary to any condition decreasing the angle between these two arteries. We recently cared for a young male who came with features of proximal small bowel obstruction. On investigation, there was extrinsic duodenal obstruction. Exploratory laparotomy was done which revealed a short and hypertrophic ligament of treitz leading to compression of 3(rd) part of duodenum. Release of the ligament with doudenojejunostomy was done. Postoperatively, patient recovered well. This case report highlights the occurrence and importance of hypertrophic and contracted ligament of treitz as a rare cause of SMAS.

Retrorectal Cystic Hamartoma: A Problematic ‘Tail’

The retrorectal space is an uncommon seat for neoplastic masses. Retrorectal hamartoma or tailgut cyst (TGC) is an uncommon developmental cystic lesion occurring in this space which mostly occurs in middle-aged females. We recently cared for a 16-year-old girl who presented with vague lower abdominal pain and occasional constipation. Per rectal examination revealed an extraluminal mass bulging from posterior rectal wall. Preoperative radiological investigations revealed by suggested it to be a mature cystic teratoma. The patient underwent exploratory laprotomy with en masse excision of the cyst. Histopathological examination of the specimen showed it to be a TGC. This case highlights the possibility of a TGC as a differential for retrorectal cystic lesions and the need to completely excise them given the possibility of future malignant transformation.

Appendicular perforation in dengue fever: our experience

Abstract Dengue viral infections have become one of major emerging infectious diseases in the tropics. Acute abdomen occurring in dengue viral infection is not uncommon. The spectrums of acute surgical emergencies which raise suspicion of an abdominal catastrophe in patients presenting with dengue fever include acute pancreatitis, acute acalculous cholecystitis, non-specific peritonitis and very rarely acute appendicitis. The presence of low white cell count and platelet count can raise suspicion of a diagnosis of dengue in a patient presenting with acute abdominal pain, during a dengue epidemic. We herein report three patients with dengue fever who had appendicular perforation during the course of their viral fever.

Uncommon Presentation of Isolated Jejunal Lymphoma Masquerading as Crohn’s Disease

Primary gastrointestinal lymphoma is a rare entity, commonly involving stomach, small bowel, and colorectum. The usual location for small bowel B cell lymphoma is distal ileum due to abundant lymphoid tissue. We are reporting the case of a 53-year-old lady presumptively diagnosed as Crohns disease on clinical and radiological grounds but histopathologically proven to be an unusual variant of isolated primary non-Hodgkins lymphoma.
