Here's the nuts and bolts of the cancer report for you science buffs:
HISTORY: Masses noticed three weeks ago.
DESCRIPTION:
Sections of all tissue from both containers is similar. Multifocally
there is a small amount of benign appearing fat and of fibrous tissue.
Much of the tissue has fairly high cellularity. Multifocally there
are considerable numbers of scattered small lymphocytes in follicular
or nodular aggregates. Many of the cells are rounded to spindle to
stellate shaped cells that vary mildly to moderately in nuclear size.
Some of them contain variably-sized single or multiple round clear
well-defined lipid type vacuoles. Mitotic figures are fairly
difficult to find. Multifocally there is mild necrosis occupying
approximately 10-20% of the section area evaluated. Agents are not
found.
MICROSCOPIC FINDINGS: LIPOSARCOMA. INFLAMED. ALL TISSUE.
PROGNOSIS: Guarded.
COMMENTS:
Given the location and the scattered inflammatory cells, this may
represent a vaccine-associated sarcoma with liposarcomatous type
differentiation. This would be an unusual manifestation in my
experience but vaccine-associated sarcomas may develop multiple
different tissue types. If there has absolutely never been a
vaccination in the region, then the cause would be unknown. The
neoplasia appears consistent with intermediate grade neoplasia.
