This paper describes the technique of lymphadenography of the dorsal lymphatics of the penis undertaken in the search for evidence of metastasis to lymph nodes in cancer of the penis and to obtain accurate location of the tributary lymphatics as a guide to complete dissection of lymph nodes. Fourteen subjects were investigated: eight normal, with no pathology of the penis; four patients with carcinoma of the penis, three of whom had injection through the stump remaining after partial amputation and unilateral dissection of lymph nodes and one given an injection into the dorsum of the penis on one side and into the dorsum of the foot on the opposite side; one patient with syphilitic chancre and one with condyloma acuminatum. This is a valuable procedure for locating and mapping distribution of lymph nodes but the interpretation of neoplastic invasion of the lymph nodes is uncertain.
Mammary hamartomas are unusual lesions with distinctive radiologic and pathologic features. They are well circumscribed, mobile tumors showing no adherence to skin or muscle. Mammographic studies show a peripheral, luscent halo, and the mass is radiographically similar in pattern to a normal breast ("breast within a breast"). Calcification is not present. Histologically, these encapsulated lesions are composed of various breast tissue components such as ducts, lobules, stroma prominently adipose, and smooth muscle, without any particular arrangement. Local surgical resection is the treatment of choice. Hamartomas of the breast are benign lesions that need to be distinguished from other breast neoplasms such as fibroadenomas, lipomas, and cystosarcoma phyllodes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
