Coexisting intraductal breast carcinoma and metastatic choriocarcinoma presenting as a breast mass

Fine Needle Aspiration Cytology of Mammary Carcinoma with Choriocarcinomatous Features

“…Although metastasis to the breast from extramammary neoplasms is rare, choriocarcinoma coexistent with infiltrating ductal carcinoma has been reported. 23 Although, most reported cases were aggressive tumors, with most patients dying shortly after initial diagnosis of widespread metastatic disease, our patients were still alive during follow-up for 6 and 4 years with no recurrences and distant metastasis.…”

Les métastases mammaires : étude anatomoclinique de six cas

“…Les sarcomes, et plus particulièrement les leiomyosarcomes, donnent rarement des métastases mammaires, à notre connaissance seulement neuf cas ont été publiés dont quatre cas étaient d'origine utérine [1,3,4,14,16,18,19]. Le choriocarcinome est également rarement à l'origine de métastase mammaire, en effet seulement dix cas ont été déjà rapportés [3,12,13,[20][21][22], dans un seul cas la méta-stase était révélatrice du choriocarcinome [21]. La plus large série de tumeurs neuroendocrine secondaires du sein est rapporté par Upalakalin et al [15] incluant 24 cas, dont neuf cas la métastase mammaire était révélatrice de la tumeur primitive.…”

Fine Needle Aspiration Cytology of Metastatic Choriocarcinoma Presenting as a Breast Lump

“…4,[7][8][9]12,13,15,16 Choriocarcinoma metastatic to the breast has been reported in 6 cases. 1,8,10,11,14,17 The cytologic diagnosis of choriocarcinoma metastatic to the breast has been reported in only 1 case, in a patient who had a previous history of uterine choriocarcinoma. 11 In contrast, the patient described in this report was noted to have a previous history of hydatidiform mole only after a histologic diagnosis of a metastatic choriocarcinoma in the nasal cavity during evaluation of the associated lung and breast masses.…”

“…1,8,10,14,17 To our knowledge, FNAC of a choriocarcinoma metastatic to the breast has been reported in only 1 case in the English-language literature and occurred in a patient with a previous history of uterine choriocarcinoma. 11 Although choriocarcinoma is a rapidly invasive, widely metastasizing malignancy, it responds well to chemotherapy, so an early diagnosis is important.…”
