Mixed malignant tumor of the submandibular gland.

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.

Metastatic primitive neuroectodermal tumor involving testis.

A 40-year-old male patient presented with enlarging mass over left leg region. Incisional biopsy report revealed an undifferentiated malignant round cell sarcoma, for which above-knee amputation was done. One year later, the same patient presented with left testicular swelling which appeared to be malignant. A left high orchiedectomy was done. Biopsy report showed metastatic round cell tumor, which was confirmed by immunohistochemistry as primitive neuroectodermal tumor. Metastasis to testis is very uncommon.

Eosinophilic enteritis presenting as a rare cause for ileo-ileal intussusception.

Eosinophilic enteritis, a relatively rare entity, usually involves gastric antrum or proximal small bowel. Our case is rarer in its involvement of the distal small bowel and presents unusually as intussusception. The disease if diagnosed in the initial stages responds well to medical treatment but if associated with complications or misdiagnosed, surgical modality is the treatment of choice. In our case, the patient presented with acute intestinal obstruction due to intussusception and emergency laparotomy with ileoileal anastomosis was done. Histopathology confirmed the diagnosis as eosinophilic enteritis. This case with such a presentation is discussed here.

Fine needle aspiration cytology diagnosis of aneurysmal bone cyst: a case report.

Aneurysmal bone cyst is a relatively rare tumour accounting 1 to 6% of all primary bone tumours. The involvement of clavicle is even rare with incidence of only 3% of all cases of aneurysmal bone cyst. Aneurysmal bone cyst is an expanding osteolytic lesion occurring mostly at metaphyseal ends of the long bones. Although excisional biopsy is diagnostic for aneurysmal bone cyst and FNAC (fine needle aspiration cytology) is mostly inconclusive. Still FNAC can be helpful in pre-operative diagnosis of aneurysmal bone cyst.

Adenoid cystic carcinoma of the male breast.

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.
