Unusual Sites of Leiomyosarcoma: A Study of 3 Interesting Cases.

Leiomyosarcoma malignant tumours arise from the smooth muscle cells. They are rapidly growing tumours with aggressive behaviour and poor prognosis. Although relatively rare, they pose a diagnostic challenge as they comprise a large spectrum of diagnostic entities. Herein, we describe three cases of leiomyosarcoma developing at unusual sites and posing diagnostic challenges. Our first case is a leiomyosarcoma developing at the post-burn scar site; the second case is of primary pulmonary leiomyosarcoma, and the third is retroperitoneal leiomyosarcoma. Histopathological examination is not sufficient all the time for making the diagnosis of leiomyosarcoma because there is a morphologic overlap with other malignancies. Immunohistochemistry acts as an adjunct to arrive at a definite diagnosis and hence, proves to be the most important ancillary technique in the diagnosis of such tumours. Though these tumours arise most commonly from the uterine smooth muscle, but rarely encountered at unusual sites posing diagnostic difficulties. Key Words: Leiomyosarcoma, Retroperitoneal, Pulmonary, Post-burn scar.

Progression of Fibroadenoma to Malignant Phyllodes Tumour in a 14-Year Female.

Phyllodes tumours are uncommon breast tumours which account for less than 1% of all breast neoplasms. High-grade malignant phyllodes tumour is a very rare but aggressive breast malignancy and forms approximately 15-30% of all phyllodes tumours. The transformation of a benign fibroadenoma into a malignant phyllodes tumour in a teenaged female is even rarer. We report here an interesting case of malignant phyllodes tumour in a 14-year female patient who was operated twice previously with the diagnosis of complex fibroadenoma in the same breast. There was a large tumour involving whole of the breast and infiltrating the skin. The patient was operated and total mastectomy was done. Diagnosis was confirmed after histopathological examination and immunohistochemistry of the resected specimen. Patient received adjuvant radiotherapy and there was no recurrence on 6-month follow-up. Owing to the rare occurrence of malignant phyllodes tumour in this age group along with previous operations for complex fibroadenoma, this case is being reported here.

Concomitant Presence of Carcinoma of Breast in a Patient with Early-Onset Cataract: First Case Report of a Potential Association.

A recent nation-wide population based retrospective cohort study from Taiwan in 2014 suggested a propensity of developing breast cancer in young females with early-onset cataract. We report here a case of a young non-obese female who presented to us with a large lump in the right breast with skin nodules and bilateral painless progressive diminution of vision. Patient was diagnosed to be suffering from locally advanced carcinoma of right breast with axillary metastasis (Stage III B) and bilateral early-onset nuclear cataract. Patient was started on taxane and anthracycline based neoadjuvant chemotherapy and after three cycles of chemotherapy patient showed partial response (≈50% reduction of tumour mass). Patient underwent small incision cataract surgery in left eye after the first cycle of chemotherapy. However, the patient was lost before any operative intervention could be done as she died in a road traffic accident. Possible mechanism of development of breast cancer in patients with early-onset cataract is discussed. This is the first reported case of a patient of early-onset cataract developing breast cancer as well as the first reported case of concomitant presence of early-onset bilateral cataract with breast cancer.

Challenges in the diagnosis and management of spontaneous bile duct perforation: A case report and review of literature.

We report a case of 14-year-old male, who presented to us with complaints of severe pain in abdomen, vomiting, and inability to pass feces and flatus. He was diagnosed as a case of peritonitis after careful history, examination, and investigations. The exact cause of peritonitis was not known. Exploratory laparotomy was done, and it was found that there was perforation of the right hepatic duct about 1 cm proximal to its confluence with the left hepatic duct. Perforation was closed around the T-tube. Postoperative T-tube cholangiogram was done after 3 weeks which confirmed the free passage of dye into the duodenum, and there was no leakage of dye. T-Tube was removed 4 weeks after the operation, and the patient was discharged in satisfactory condition. Postoperative follow-up was done for 3 months, and it was uneventful.

A case of coexisting carcinoma and tuberculosis in one breast.

Coexistent carcinoma and tuberculosis in a breast is a rare entity. It poses problems right from the diagnosis and staging of carcinoma to treatment and patient compliance. Proper clinical examination and investigations should be performed in such cases as both carcinoma and tuberculosis are major diseases with no definite symptoms or signs to distinguish the two. Herein, we report the case of a 45-year-old female who presented with complaints of a lump and pain in left breast, weight loss and weakness for the past 4 months. Fine needle aspiration cytology from the breast lump showed clusters of malignant cells along with many loose clusters of epithelioid cells on a background showing caseous necrosis. A diagnosis of coexisting breast carcinoma and tuberculosis of the breast was made and antitubercular treatment was started. The patient was operated and histopathology confirmed the diagnosis.

Megaloblastic anemia: A common but often neglected cause of pyrexia of unknown origin.

OBJECTIVE: The objective was to study megaloblastic anemia as a cause of pyrexia of unknown origin (PUO). MATERIALS AND METHODS: We conducted a study on 15 patients of megaloblastic anemia associated with fever, attending our hospital clinics over a period of 6 months. RESULTS: While 11 patients had symptoms suggesting foci of infection and responded well to intravenous antibiotics, 4 patients had neither any evidence of infection nor responded with empirical broad spectrum antibiotic treatment. They were treated with vitamin B12/folate therapy which led to marked improvement in fever within 48 h. Presenting complaints of the patients and severity/duration of fever along with other epidemiological data were also studied in each case. CONCLUSION: The present study led us to conclude that megaloblastic anemia forms an important and reversible cause of fever and should be ruled out in all patients presenting with PUO. This knowledge would help the physicians in adequate and timely management of these patients.

Primary hydatid disease of the breast clinically masquerading as a galactocele: A case report.

We report a rare case of a 30-year-old breastfeeding woman who presented to our surgical outpatient department with complaints of a gradually enlarging lump in her left breast for the last 2 months. She also complained of difficulty in breastfeeding for 1 week. On examination, the right breast was normal but there was a 4 cm × 4 cm retroareolar soft lump in her left breast. Examination of the bilateral axilla was normal. A provisional diagnosis of galactocele was made and the patient was subjected to ultrasonic mammography and fine needle aspiration cytology (FNAC). Ultrasonic mammography of the left breast showed a heterogeneous, hypoechoic lesion with thick septations and internal echoes suggestive of a complex cystic lesion, leading to a differential diagnosis of either hydatid cyst or breast abscess. On FNAC, the aspirate was not milky and cytological examination was performed, which revealed hydatid scolices, hooklets, foamy macrophages and granular debris, leading to the final diagnosis of hydatid cyst of the breast. The patient was investigated further but there were no cysts at any other site. Chemotherapy with albendazole was started and surgery was performed after 1 month. Histopathology further confirmed the diagnosis. Owing to the rarity of presentation, this case is being reported here.

Late Post Traumatic Right-sided Diaphragmatic Hernia Presenting with Acute Intestinal Obstruction and Strangulation: A Rare Presentation.

We report a case of 16 year old male, who was presented to Jawaharlal Nehru Medical College, AMU, Aligarh, India as an emergency case with complaints of severe abdominal pain, difficulty in breathing and bilious vomiting. He was diagnosed as a case of late post traumatic right side diaphragmatic hernia with acute intestinal obstruction. He was successfully treated surgically by laparotomy and the defect was closed with polypropylene suture. The patient was followed for 3 months after operation and there was no complication.
