- A dedifferentiated liposarcoma is a uncommon neoplasm characterized by the coexistence of a well-differentiated liposarcoma and non-lipogenic sarcomas. A peculiar neural-like or meningothelial-like whorling pattern of dedifferentiation has recently been reported. We report a case of dedifferentiated liposarcoma with a peculiar whorling pattern in the scrotum of a 76-year-old man.
Histologically, the tumor consisted of areas of a well differentiated liposarcoma admixed with areas of a morphologically non-lipogenic sarcoma. The whorls were scattered throughout the tumor. The cells in the whorls and dedifferentiated area showed a significant nuclear PCNA and p53 protein reactivity.

Abstract
PDF
- Tubulolobular carcinoma is a tumor of the breast that shares histologic features of both tubular and lobular carcinoma of the breast. The cytologic features of this neoplasm have not been reported in Korea. We described a case of tubulolobular carcinoma diagnosed by fine needle aspiration cytology in a 46-year-old female. The tumor contained several cytologic features of both tubular and lobuar carcinoma, including tubular structures, single filing of cells, intracytoplasmic vacuoles, and low nuclear grade.

Abstract
PDF
- Mixed lobular and ductal carcinoma in situ is very rare. We recently experienced a case of invasive lobular carcinoma associated with mixed lobular and ductal carcinoma in situ in a 50-year-old female. The infiltrating portions of lobular carcinoma revealed thread-like strands of tumor cells. Lobular carcinoma in situ with pagetoid spread into the ducts and ductal carcinoma in situ of the predominantly papillary type were also noted in the same mass.
