Radiological Manifestations of Ectopic Salivary Adenomas Showing the Cylindroma Pattern

Dermatoscopic pattern of a cylindroma

A 65-year-old man presented with an asymptomatic lesion on the left parietal scalp of 6 months’ duration. Three years prior, a cylindroma on the same area was excised by a general surgeon. Physical examination revealed a solitary 6 mm salmon-pink, firm, dome-shaped papule on the left parietal scalp (Figure 1).

Multiple ectopic parathyroid adenomas.

CONTEXT Primary hyperparathyroidism is the most common cause of hypercalcemia in unselected patients. The ectopic gland locations should be known for appropriate surgical exploration and for avoiding subsequent re-exploration that would represent higher morbidity. Multiple ectopic glands are rare and present a particular challenge in parathyroid surgery. CASE REPORT A 65-year-old female prese...

Invasion of cranial nerves by salivary cylindroma : four cases treated

Four cases of adenoid cystic carcinoma (cylindroma) of accessory salivary tissue are described, and the diagnostic difficulties experienced are emphasized. The tumour infiltrates cranial and other nerves and may invade the central nervous system by this route. It is highly malignant and may metastasize widely both by haematogenous and lymphatic pathways. The tumour is radiosensitive and it is s...

Radiological manifestations of primary gout.

Gout is an ancient disease not uncommonly seen in radiological practice. Twenty-two patients of suspected gout were examined over a period of 11 years (1984-1995). There were 20 males and 2 females with ages between 35-70 years. First metatarsophalangeal joint was involved in 18 patients. Tophaceous deposits in hands were seen in one, whereas another patient had urate deposit in the lateral con...
