Uterine Leiomyoma with Massive Lymphocytic Infiltration.: Won Mi Lee, Moon Hyang Park; Korean J Pathol. 2003;37(1):71-73.

Abstract PDF: Uterine leiomyoma with massive lymphocytic infiltration is known to be associated with Gona-dotropin releasing hormone (GnRH) agonist treatment. The lymphocytic cells in those cases were composed predominantly of T-lymphocytes. We report an unusual case of uterine leiomyoma with massive lymphocytic infiltration, composed predominantly of B-lymphocytes, without a history of GnRH agonist treatment. A 59-year-old woman underwent a transvaginal hysterectomy for uterine leiomyomas. Microscopically, the leiomyoma showed a massive infiltration of the lymphocytes, histiocytes, and also showed scattered plasma cells and many lymphoid follicles. The lymphocytic infiltrates were confined to the leiomyoma. These lymphocytic cells mainly represented the B-cell phenotype. She had no history of GnRH agonist treatment. To the best of our knowledge, This is the first reported case in Korea.

Yellowish Degeneration of Uterine Leiomyomas: Light Microscopic and Ultrastructural Observations.: So Dug Lim, Joo Ryung Huh, Yong Il Kim; Korean J Pathol. 1995;29(2):221-227.

Abstract PDF: We reviewed five cases of Uterine leiomyomas, each with a conspicuously, yellow cut surface, among 198 consecutive cases of surgically removed uterine leiomyomas. Their gross findings were not significantly different from ordinary leiomyomas except for their pale to bright Yellowish cut surface. Microscopically, multiple small clusters of clear cells were widely scattered in otherwise hypercellular leiomyornas in 4 of the 5 cases. Of those, one case gave a positive reaction of Oil-Red O stain. Ultrastructurally, clear cells corresponded to the degenerating smooth muscle cells with intracytoplasmic lipid vacuoles. The rest of cells showed myofibers undergoing varying degrees of degeneration. Focal accumulation of foamy histiocytes was associated with carneous degeneration in one case. We conclude that the yellowish leiomyoma of the uterus seems, in part, to reflect accumulation of a lipid substance in degenerating hypercellular leiornyoma, or possibly collections of xanthoma cells in secondary degeneration.
