Carcinoma papilar de tiroides: úlcera sangrante de piel / Thyroid cancer and bleeding skin ulcer

Background: Differentiated thyroid cancer has a good prognosis. If there is local tumor infiltration, the prognosis depends on its complete excision. Case report: We report a 67 years old woman with a papillary thyroid cancer and a bleeding skin ulcer. The initial assessment disclosed local tumor infiltration of neck structures and cervical lymph nodes. She was subjected to a radical thyroidectomy, radical neck dissection and dissection of involved structures. She was also treated with radioiodine and levothyroxine and remains asymptomatic after two years of follow up.

Introducción: Los cánceres tiroideos, de la variedad diferenciada, son tumores malignos con buen pronóstico. Los subtipos más comunes son el carcinoma papilar y el carcinoma folicular. Incluso cuando infiltran localmente, tienen un pronóstico relativamente bueno cuando se pueden resecar completamente. Caso clínico: Presentamos un caso de cáncer papilar de una señora mayor que se presentó con una úlcera sangrante de piel. En la evaluación se encontró que tenía infiltración de estructuras del cuello locales y de los ganglios linfáticos cervicales. Fue tratada con tiroidectomía total y disección radical de cuello modificada, así como la resección de las estructuras involucradas. Más tarde fue tratada con yodo radiactivo y levo tiroxina. A pesar de la infiltración local permanece asintomática a los dos años de seguimiento.

Small Bowel Melanoma Metastasing to Inguinal Lymph Node - a Rare Case.

Malignant Melanoma is one of the commonest cutaneous malignancies affecting human beings. The gastrointestinal tract is a common site for melanoma, both as primary and metastases. However it is rare for gastrointestinal melanoma to metastase oustide of the abdominal cavity. In the literature, there is no evidence about inguinal lymph node metastases from small bowel melanoma. Here we present a case report of an old lady who underwent laparoscopic resection of small bowel for melanoma and presented 4 years later with metastatic lymph node in inguinal lymph node. Though it could not be verified, we hypothesise that the tumour disseminated to the lymph node through a port-site metastases. Literature review shows several mechanisms which were put forward to explain the mechanism of port-site metastases.

Skeletal muscle metastases from pancreatic carcinoma-a case report and review of literature.

With an overall mortality approaching nearly 100 %, pancreatic cancer is still a challenging disease. A major proportion of pancreatic cancers are still diagnosed at the locally advanced or metastatic stage. Tumors originating from tail region present very late due to the absence of specific symptoms and signs. The usual sites of metastases are the liver, peritoneum and lungs, with occasional reports of metastases in other sites. There are very few documented cases of gastrointestinal cancers manifesting as metastases to muscle. This is a report on a case of pancreatic cancer presenting as metastases to skeletal muscle and multiple other viscera and review of literature for pancreatic cancer metastases.
