Fine-needle aspiration cytology of soft-tissue calcinosis presenting as an enlarging mass in the chest wall

Clinicopathological findings in five cats with paw calcification

This retrospective study describes the clinicopathological findings in five cats with soft tissue mineralisation of interdigital spaces and footpads. Paw disease was the reason for veterinary consultation in three out of five cats. All cats had laboratory findings suggestive of renal failure and high solubility product [calciumxphosphorus]. In all cases, cytological examination of paw lesions was suggestive of calcinosis. The results of our study agree with two previous case reports of paw calcification in the cat, suggesting a metastatic pathogenesis and a correlation between paw mineralisation and renal failure.

Aspiration cytodiagnosis of the breast with abundant acellular calcific material indicative of soft tissue calcinosis (a study of 3 cases)

Calcific deposits in soft tissue are rare and may clinically resemble a tumour. It seems feasible, therefore, to investigate them by the non-invasive technique of fine needle aspiration cytology (FNAC). In this study three cases with extensive accumulation of acellular calcific material in the breast are described in which FNAC was indicative of soft tissue calcinosis. In all cases routine mammogram had shown a partially cystic opacity. All other investigations were normal and no significant family or medical history was present. Cytopreparations in all cases showed only abundant acellular calcium. The patients had no further treatment and on follow up were clinically well with no changes. The cases are interesting, since the cytohistological findings in the aspirate sample appeared to be strongly indicative of soft tissue calcinosis.

Fine-needle aspiration cytology of the breast in a case with abundant acellular calcific material indicative of soft-tissue calcinosis

Since calcific deposits in soft tissue may clinically resemble a tumor, it is feasible to investigate them by fine-needle aspiration (FNA) cytology. In this presentation we describe a case in the breast with extensive accumulation of acellular liquid calcific material which was sampled by the noninvasive technique of FNA, and which was indicative of nonfamilial soft-tissue calcinosis. A 48-yr-old, perimenopausal woman on a routine mammogram showed a well-defined, 1-cm partially cystic opacity in the left upper quadrant of the breast. All other investigations were normal, and no significant family or medical history was present. Under ultrasound guidance FNA was done, and about 1 ml of thick whitish fluid was obtained. Cytopreparations only showed abundant acellular calcium. The patient refused any further treatment and elected to be under the care of her family physician, according to whom she was clinically well with no changes in mammograms for the last 2 yr. The case is interesting, since the cytohistologic findings in aspirate sample appeared to be strongly indicative of soft-tissue calcinosis, which to our knowledge has not been previously reported.
