Histologic confirmation- ... where a skin biopsy specimen was obtained.
However, this was only seen after subserial sectioning of the biopsy specimen

Mucosae were fixed in buffered 5% formol-saline, divided lengthwise into two blocks and embedded in paraffin wax. Subserial sections, 3-5 from each block, were stained with haematoxylin and eosin

Every tenth section (30 (im thick) was saved, and the bulk of subserial sections from individual segments (10 to 25 sections) was processed separately

Subserial sectioning of the specimens permitted determination of the type, number, and extent of noncancerous mucosal lesions and their exact location in relation to the carcinomas.

The solitary residual tumor is most common, but main residual tumors with satellite lesions are most likely to cause local recurrence after BCS, and subserial sectioning would improve the identification of microfoci and patient survival

The cases of two patients with diffuse toxic goiter, in which psammoma bodies were microscopically observed, are presented and subserial sectioning of both thyroid glands failed to disclose occult carcinoma
