We observed a 73-year-old man with necrobiotic xanthogranuloma (NXG) on the eyelids and concurrent multiple myeloma. The treatment was surgery followed by administration of melphalan. No relapse was seen in 19 months of follow-up. We consider that surgical removal of xanthogranuloma is an advisable rapid treatment that involves fewer side-effects than other treatments.

A 65-year-old woman on whom a cardiac catherization using iodine contrast had been performed developed 5 days later acute renal failure, respiratory insufficiency and cutaneous lesions consisting of two great vegetating masses located on both cheeks and pustular vesicular lesions on the extremities. A fortnight later, the patient died. We would like to stress this case because of the exceptional nature of vegetating iododerma at present, and the importance of recognizing a possibly fatal disease.

3D (1.2 mm (0.6 to 3)) without significant difference, probably due to ''In to In'' assessement. 25 cases of 2D NT measurements were associated with a low Herman score (<6). 23 of these 25 cases were associated with better Herman score (≥6) using Volume NT and even those measured by the least experienced operator (p = 0.035). Conclusions: Volume NTTM helps to improve Herman score, whenever 2D NT assessment is difficult to get, by obtaining a better sagittal plane, even in the hands of a less experienced operator.

RESUMEN "LIPOSARCOMA DEDIFERENCIADO DEL CORDÓN ESPERMÁTICO: DEGENERACIÓN DE UN LIPOMA PREVIO RESECADO" Los sarcomas del cordón espermático son tumores de rara presentación. El liposarcoma dedife-renciado representa sólo un 10% de los sarcomas del cordón espermático. Estos suelen ser tumores de gran tamaño y con una histología caracterizada por ser un liposarcoma bien diferenciado con áreas de sarcoma de alto grado. El TAC y la ecografía nos informarán del volumen, localización, homogeneidad de la masa, así como de las posibles adenopatías pelvianas y retroperitoneales. Son útiles en el seguimiento después del tratamiento. Nosotros presentamos un liposarcoma dediferen-ciado, de cordón espermático, al que previamente, se le extirpó en tres ocasiones lipomas en el mismo cordón espermático. Creemos que se trata de una degeneración del lipoma previo resecado. El tratamiento es la orquiectomía radical por vía inguinal amplia, siendo la radioterapia y la qui-mioterapia de ayuda complementaria, con valor incierto. Suelen presentar recidivas locales frecuen-tes después de la cirugía, pudiendo presentar metástasis hematógenas y en nódulos pelvianos. Presentan una supervivencia a los 5 y 10 años, de un 75% y 63% respectivamente. PALABRAS CLAVE: Liposarcoma dediferenciado. Cordón espermático. Degeneración lipoma. ABSTRACT "DEDIFFERENTIATED LIPOSARCOMA OF SPERMATIC CORD: DEGENERATION LIPOMA RESECTION PREVIOUS" Spermatic cord sarcomas are rare tumours. Dedifferentiated liposarcoma accounts for only 10% of all spermatic cord sarcomas. These are usually large-sized tumours histologically characterised for being well-differentiated liposarcomas with some high grade sarcoma areas. Volume, location, mass homogeneity as well as presence of pelvic and retroperitoneal adenopathies are reported by CT and ultrasound techniques. These are useful for post-treatment follow-up. This paper presents one spermatic cord, dedifferentiated liposarcoma from which lipomas from the same spermatic cord had been previously removed in three occasions. We believe this is a degeneration of the earlier resected lipoma. Management is by extended inguinal radical orchiectomy. Value of adjuvant radio-and che-motherapy is uncertain. Post-surgery local relapses are common, and haematogenous and pelvic nodes metastasis likely. Survival at 5 and 10 years is 75% and 63% respectively.
