“…Often these follicles have been called parathyroid cysts. Typical cysts in parathyroid glands have been reported before only occasionally (Godwin, 1937b;Rother and Wendler, 1968;Pemsingh et al, 1985). The differences between the cysts in parathyroid I11 and these in parathyroid IV have been clarified in the present study.…”

Cyst structures were often detected in and around thyroid glands of the dog. The present study revealed the frequency of occurrence, the light microscopic features, and the immunoperoxidase reactions to anti-keratin and anti-19S-thyroglobulin antisera of each cyst located in parathyroid III, parathyroid IV, thymus IV, C-cell complexes, and thyroid parenchyma from 112 dogs. In each location, cysts showed characteristic features. In parathyroid III, the cysts were covered with single or pseudostratified epithelium composed of ciliated cells; whereas in parathyroid IV they were covered with keratinizing stratified squamous epithelium. In C-cell complexes, small cysts lined with small packed cells were predominant, and large cysts lined with single cuboidal cells or stratified squamous cells were also present. In thymus IV located in the close vicinity of parathyroid IV, cyst epithelium consisted of several types of cells showing variable features. In thyroid parenchyma, there were several types of cysts: some were covered with ciliated columnar cells, and others were covered with two or multilayers of small packed cells or cuboidal cells. In spite of these differences in appearance of the cysts located in different tissues, all their epithelia were immunoreactive to the keratin antisera, except for small cysts in C-cell complexes, which were regarded as immature structures. Thus, the presence of keratin filaments in epithelial cells seems to be a characteristic feature of all cysts. The lumens of each cyst contained variable amounts of amorphous materials, which showed colloid-like, flocculent, foamy, and granular features and were periodic acid-Schiff-positive in variable degrees, from weak to intense. Although the lumenal contents of the cysts in parathyroid III revealed no immunoreactivity for 19S-thyroglobulin, those in thyroid parenchyma, C-cell complexes, parathyroid IV, and thymus IV reacted strongly with the 19S-thyroglobulin antiserum.

“…Pearse et al (1972) suggested that the autofluorescence of some amyloids is due to tryptophan, tryptophan metabolites, or possibly to transfer of the excited state from nearby tyrosine molecules (Kronman and Holmes, 1971). Rother (1970) believes that some parathyroid follicles are involved in the production or storage of hormone, but the nature of the hormone is uncertain. Leedham and Pollock (1970) favoured an association of amyloid with calcitonin production, a process for which there is some evidence from human parathyroid gland extracts (Galante, Gudmundsson, Matthews, Tse, Williams, Woodhouse, and Mac-Intyre, 1968) despite lack of histological evidence for cells of the APUD system in human parathyroid glands.…”

SYNOPSIS Two groups of parathyroid glands have been examined for intrafollicular amyloid. In glands removed surgically it was found in nine cases (16 Y.); in glands removed at necropsy it was found in 23 cases (46 %). Also, two postmortem cases of systemic amyloidosis showed involvement of parathyroid glands with an entirely different distribution of amyloid. Compared with other amyloids the tinctorial properties of the intrafollicular amyloid were uniform in reactions with Congo red and Thioflavin T, but the intensity of the staining reaction for amino acids tryptophan and tyrosine was not constant for the follicle amyloid. This variation may be a feature of a maturation process but the derivation of this amyloid remains uncertain.
