Ovarian androblastoma metastatic to tonsil

Abstract

Structural pattern of a tonsillar tumor found in a 67-year-old female was similar to a small ovarian androblastoma diagnosed histologically 6 1/2 years earlier. Electron microscopic study of the tonsillar mass revealed crystalloid structures suggestive of the Leydig cell origin of the tumor. After tonsillectomy, there was no local recurrence of the tumor, but the patient died a year later of multiple metastases. There appeared to be no previous reports of ovarian tumors metastatic to tonsil, and malignant androblastomas of the Leydig cell type are extremely rare.

Phyllodes tumor metastasis to the tonsil with synchronous undifferentiated carcinoma

“…The cases reported involved metastasis from cutaneous or mucosal melanoma, 2,3 gastric adenocarcinoma, 4,5 hypernephroma, 6,7 and various lung neoplasms 8 . The less common metastatic tonsillar tumors originate from mesothelioma, 9 hepatocellular carcinoma, 10 ovarian androblastoma, 11 seminoma, 12 anaplastic thyroid carcinoma, 13 pancreatic adenocarcinoma, 14 prostatic adenocarcinoma, 15 and gall bladder carcinoma 16 . Breast carcinoma is one of the rarest primary tumors that can metastasize to the tonsil; only eight cases have been reported in the literature, 17 and only one case of tonsillar metastasis of breast sarcoma has been reported 18 …”

A case of Merkel-cell carcinoma metastatic to the tonsil

“…Carcinoma of the stomach and pancreas and seminoma of the testis metastasizing to the tonsil have been described, but are less common (Brownson et al, 1979;Passmoreetal., 1982;Maoretal., 1983;Galloetal., 1992). Isolated cases of tonsillar metastases from prostatic adenocarcinoma (Stern, 1923), pyriform sinus carcinoma (Kaufmann, 1931), ovarian androblastoma (Bychko et al, 1984), gall bladder carcinoma (Asami et al, 1989), anaplastic thyroid carcinoma (Hadar et al, 1987) have all been documented. Reports of Merkel-cell carcinoma metastasizing to the palatine tonsil have not been described.…”

Anaplastic small cell (oat cell) carcinoma of the tonsils: report of two cases

“…The simultaneous presence of tonsillar and bronchial tumours in case 2, raises the question whether both lesions are authentic primaries or whether the former could be a metastasis of the latter or vice versa? Metastases to the tonsils are unusual and reports are usually of single cases: melanoma of skin (Craig, Glass & Rhyne 1982, Myer, Wood & Donegan 1983; carcinoma of breast (Barton et al 1980, Lee, Fischer & Fappiano 1987, stomach (Passmore, Hugh & Coleman 1982), pancreas (Feleppa & Ellison 1981, Maor, Tovi & Saks 1983), and kidney (Brownson et al 1979, Bom & Baarsma 1982; and arrhenoblastoma of ovary (Bychkov et al 1984). In a personal experience extending over 10 years we have seen only one case of tonsillar metastasis, from a generalized melanoma.…”
