Cervical Cystic Lymphangiomas in Adults: A Case Series of a Rare Entity with Literature Review.

Cystic lymphangiomas (CLs) are benign congenital lymphatic malformations that are thought to represent developmental abnormalities rather than true neoplasms. The head and neck region is the most common site of occurrence, although CLs can be present elsewhere in the body including the axilla, mediastinum, groin, and retroperitoneum. More than 80% of CLs present before the age of two. Occurrence in adults is rare with only a few cases reported in the literature. We describe five cases of cervical CLs in adults and discuss imaging modalities used for diagnostics, clinicopathologic features, and therapeutic options.

Parathyroid lipoadenoma: case report and review of the literature.

Parathyroid lipoadenoma is a rare variant of parathyroid adenoma showing intermingling of chief/ oxyphil cells with abundant mature adipose cells, the latter comprising 20-90% of the tumour. Approximately thirty-five cases have been reported previously. We report a case of 41-year old woman who presented with clinical manifestations of primary hyperparathyroidism. She had elevated serum calcium and parathyroid hormone levels. Radiological investigations suggested presence of adenoma. Intra-operatively, parathyroid adenoma was found in the neck in an ectopic location behind the carotid sheath and extending into the superior mediastinum. Clinicopathological findings of this rare tumour are discussed.

Role of radiotherapy in a recurrent aneurysmal bone cyst of the temporal bone: case report.

OBJECTIVE AND IMPORTANCE: A rare case of aneurysmal bone cyst (ABC) of the temporal bone is presented which, following recurrence after surgery, was successfully treated with radiotherapy. The role of radiotherapy in such cases is reviewed. CLINICAL PRESENTATION: A 30-year-old man presented with a recurrent swelling and pain in right temporal region following surgery for ABC at that site. INTERVENTION: Local radiotherapy to a dose of 31.5 Gy in 18 fractions over 3.5 weeks was delivered to the site of recurrence. The patient had a near total regression of the ABC as evident clinically and on radiological images. CONCLUSION: To the best of our knowledge, radiation for the recurrent ABC at the temporal bone has not been described in the literature. However, in view of the response evident in this patient, radiotherapy seems to be effective for recurrent cases of ABC at the temporal bone and a dose of around 30 to 36 Gy could be effectively delivered with satisfactory results.
