CONTEXT: Lymph node metastasis has an important bearing on the staging of breast cancer. Lymph node metastasis occurs by hematogenous and lymphatic spread. The hematogenous and lymphatic spread can be quantified by the blood vessel and lymphatic vessel density in the intra-tumoral and peri-tumoral zone by specific markers for blood vessels and lymph vessels. AIMS: In this study, we are trying to study the localization of podoplanin in lymph vessels of invasive breast carcinoma, to quantify lymphangiogenesis in tissue sections of invasive breast carcinomas by podoplanin immunohistochemistry (IHC) by D2-40 antibody, and compare it with blood microvessel count using CD-31 antibody and correlating clinicopathologic parameters with the results of IHC. MATERIALS AND METHODS: IHC for biomarkers D2-40 and CD-31 were performed on sections from 30 mastectomy specimens to assess blood vessel and lymphatic vessel density in intra-tumoral and peri-tumoral zone. The data were analyzed using Statistical Package for Social Sciences (SPSS) version 15.0 statistical analysis software. RESULTS: The results showed that both lymph vessel density and blood vessel density increased with the increase in lymph node ratio. Lymph node ratio is the ratio of positive lymph nodes to the total number of lymph nodes removed. CONCLUSION: Taking into account our small sample size, we conclude that a further large-sized study should be carried out to further prove the role of lymphatics in tumor dissemination. New therapeutic options can be developed targeting the lymphatic channels to arrest the lymphatic spread of the breast cancer.

Lipoleiomyoma of uterus are a rare variant of uterine leiomyoma. Clinically the symptoms are indistinguishable from an ordinary leiomyoma. It is diagnosed pre-operatively as leiomyoma or mature ovarian teratoma. Majority of them are post operative chance finding. Solid tumors of broad ligament are also rare. Most of them are lateral extensions from the uterine tumors. Primary lipomas of broad ligament are rare. They are asymptomatic in majority of cases and are incidental post-operative finding. We report this case because of the rarity of individual lesions and rarity of the combination and also speculate their histogenesis as adipose tissue is rare absent at both locations.

Multilocular cystic renal cell carcinoma (MCRCC) represents a rare variant of clear cell renal cell carcinoma (RCC). MCRCC has been recognized as a separate subtype of RCC in the 2004 World Health Organization (WHO) classification of adult renal tumors. MCRCC is diagnosed on the basis of strict histological criteria according to 2004 WHO classification. The chief differentials diagnosis to be considered include cystic nephroma, cystic clear cell carcinoma, clear cell papillary renal cell carcinoma and tubulocystic carcinoma. Only few cases of MCRCC are reported in literature. This case is being highlighted for its rarity and so as to avoid a misdiagnosis as conventional RCC.
