Abstract

A 66-year-old woman had a long-standing, scaly erythematous lesion on her left temple which histologically showed features of amelanotic lentigo maligna. It had recurred on numerous occasions over a period of 17 years, in spite of multiple attempts at curative surgery. There were also recurrences within a skin graft which, to our knowledge, has not been documented previously with lentigo maligna. In spite of the prolonged course, and extensive intraepidermal melanocytic proliferation amounting to melanoma in situ, there has been no evidence of dermal invasion. The lack of pigmentation in such lesions means that clinical definition of margins is highly inaccurate. In view of the aggressive horizontal growth phase of this lesion, with rapid recurrence following surgery, it was treated with electron beam therapy, and this has resulted in complete clinical remission. This most unusual case illustrates the potential difficulties in diagnosis and management of amelanotic lentigo maligna.

[Fibromyalgia. Diagnostics--disease approach--therapy].

Fibromyalgia is a complex of symptoms predominantly affecting females and consisting of widespread pain. Etiology and pathogenesis are not sufficiently known yet, however, there is the assumption that fibromyalgia is looked at as being an illness with biological, psychological, and social aspects. Therefore, the treatment of fibromyalgia calls for a multimodal therapy approach. The importance of fibromyalgia has been recognized within the German health system by creating the new ICD code M79.70 and by assigning fibromyalgia its own rheumatologic DRG (I79Z). In future research of fibromyalgia special attention needs to be placed upon gender-specific problems.

Lack of survival benefit of post-operative radiation therapy in prostate cancer patients with positive lymph nodes.

Randomized data from SWOG 8794 and EORTC 22911 confirm the benefit of post-operative radiation therapy (RT) for selected patients with pT3 prostate cancer (CaP) after radical prostatectomy (RP). However, data regarding the potential benefit of RT for patients post-RP with positive lymph node (+LN) involvement are limited. We analyzed the Surveillance Epidemiology End Results (SEER) registry for population-based data on efficacy of post-operative RT for +LN patients after RP. As LN data have only been captured by SEER since 1988, we analyzed data for 1988-1992, with specific attention to 10-year relative survival (defined as observed survival divided by the survival of a gender-, age- and race-matched population cohort without disease). Specifically analyzed were data for 1921 patients with nonmetastatic prostate cancer who underwent surgery alone, or surgery followed by RT, and who had +LNs documented. SEER does not code the interval between surgery and RT, so the ratio of patients receiving salvage versus adjuvant therapy is unknown. Using follow-up data through 2002, post-diagnosis survival was examined by number of +LNs. There was no significant relative survival benefit for +LN patients receiving post-operative RT (chi(2)P=0.270). These data do not support routine use of post-operative RT for patients with +LNs in the surgical specimen.
