[Evanescent toxic thyroid adenoma. Possible role of phenylpropanolamine].

A patient with a toxic adenoma, already reduced in size by TSH, presented on the third day after treatment of a common cold by phenylpropanolomine, a severe pain in the thyroid gland. 4 weeks later, the nodule, which measured 3 x 4 cm. had clinically disappeared and the scan returned to normal. The disappearance 5 months later of the antithyroid antibodies confirmed the cure. Catecholamines, stimulating the production of thyroid hormone and producing temporary ischemia of the gland, phenylpropanolamine, a sympathomimetic drug, may have caused hemorrhagic necrosis of the adenoma and its disappearance.

A new familial cancer syndrome? A spectrum of malignant and benign tumors including retinoblastoma, carcinoma of the bladder and other genitourinary tumors, thyroid adenoma, and a probable case of multifocal osteosarcoma.

An 11-year-old Caucasian girl who had been cured of bilateral retinoblastoma developed non-radiation-induced osteosarcoma in multiple sites of the extremities. Investigation of the medical histories of 36 of her family members through six generations revealed that 8 relatives on the maternal side (22%) had malignant tumors, predominately genitourinary carcinomas, 2(6%) had benign tumors only, and 2(6%) had both benign and malignant neoplasms. The histologic variety of these tumors, the predominance of genitourinary carcinoma, the higher than expected frequency of tumor appearance over six generations, and the occurrence of malignant tumors in direct lineage suggest that the case of retinoblastoma followed by osteosarcoma is part of a familial cancer syndrome.

Immunhistochemical and electron microscope analysis of adenomas of the thyroid gland. I. A comparative investigation of hot and cold nodules.

Histologic, immunhistochemical and electron microscopic changes in 8 cases of scintigraphically proven autonomous thyroid adenomas are described and compared with non-functioning adenomas. Adenomas with a light microscopic appearance suggesting autonomy show follicles which are mainly small or normal sized and lined by columnar thyroid cells with a partly vacuolated and eosinophilic cytoplasm. Immunhistochemically a high content of thyroglobulin corresponds to the amount of rough endoplasmatic reticulum. Typical ultrastructural criteria are a well developed cytocavitary network, numerous mainly apically localized lysosomes, prominent Golgi fields with sprouting vesicles and autophagic vacuoles. The cell surface is, when compared to non-functioning adenomas, enlared apically by numerous long microvilli and basally by deep infoldings. On contrast to experimentally TSH-stimulated animal thyroids, colloid droplets and pseudopodia are rare. The morphological findings are compared with recent biochemical results and the diagnostic value of electron microscopy is discussed.

C cell adenoma of the human thyroid gland.

A case of C cell thyroid adenoma in a 47-year-old female patient is described. The nodule showed progression over 34 years. The adenoma cells showed histochemical and ultrastructural properties characteristic for C cells. Histologic examination revealed no atypical features of nodule cells nor infiltration of capsule by neoplastic cells. In the period of 8 years following the excision there was neither recurrence nor metastases.
