RESUMEN
A 70-year-old woman presented with chief complaints of swelling in the right side of her neck for 20 years, mainly in the submandibular region, with an increase in size 2 months prior, discharge of foul-smelling pus, ulceration of the overlying skin, and pain in the swelling for 15 days. Immunohistochemical studies reported the tumor to be a mixed malignant tumor arising from the submandibular gland. Wide excision of the tumor with deltopectoral flap was done.

Carcinoids are solid tumors of entero-chromaffin origin classified as neuroendocrine amine precursor uptake and decarboxylation (APUD) cell tumors and are found throughout the gastrointestinal tract from the stomach to the rectum, with a predilection for the ileum. These tumors rarely occur in the stomach, constituting only 2% of gastric tumors and 3.3% of all carcinoid tumors of the gastrointestinal tract. Localization of gastric tumors can be done by ultrasonography, computed tomography, and magnetic resonance imaging, but endoscopic biopsy is required for confirmation; demonstration of neurosecretory granules on microscopy is the most specific feature. Early resection is the treatment of choice. Prognosis of noninvasive tumors <2 cm in size in terms of 5-year survival rate is 100%. The 5-year survival rate declines and prognosis becomes poor with increase in size and with involvement of serosa, perineural infiltration, and lymph node metastasis.

An 18-year-old man presented with complaints of epigastric pain, vomiting after meals, loss of appetite and weight, evening rise of temperature, and irregular bowel movements. Barium meal follow-through revealed a dilated stomach and first and second parts of the duodenum and stenotic lesion in the second part of the duodenum. Endoscopic biopsy of the stenotic lesion revealed acute on chronic nonspecific duodenitis with fibrosis. Isoperistaltic antecolic gastrojejunostomy was done to bypass the obstruction, and enlarged lymph nodes were biopsied. The biopsy of the enlarged lymph nodes revealed changes consistent with tuberculosis; therefore, the patient was started on antituberculous drugs in the postoperative period.

We present an 82-year-old male patient who presented with complaints of gradually an increasing ulcero-proliferative lesion with persistent mucinous discharge in the left breast. Left side-modified radical mastectomy was done. This was histopathologically diagnosed as an adenoid cystic carcinoma of the left breast. Periodic acid schiff (PAS) staining confirmed the diagnosis. Three of the five axillary lymph nodes excised were positive for malignancy. Although the patient was advised to have postoperative radiotherapy, he did not comply. After 2 years, the patient again presented with local recurrence of the disease. Wide excision of the recurrent malignant nodules over the anterior chest wall was done, and the defect was covered primarily with split thickness skin grafting. Postoperative radiation was given. For the past 9 months, the patient has maintained a regular follow-up on an outpatient basis. He does not have any evidence of recurrence of the tumor--neither locally nor distant metastasis.
