The university museum for cultural history in the castle of Marburg has a portrait "Die grosse Barb", which represents a women suffering from acromegaly. She shows the typical pathologic alterations: thickening of the skin folds, thickening of the lips and the eyelids, growth of bones and cartilages, lengthening of the nose, enlargement of the ears, protrusion of the zygoma, mandible and the chin. Acromegaly is a consequence of enhanced secretion of growth hormone, which occurs also as a symptom of several syndromes, such as multiple endocrine neoplasia type 1, McCune-Albright-syndrome, and NAME syndrome (Carney complex type I).

In the case of metastatic spread the patient has a poor long-term prognosis. We hope to familiarize dermatologists and other specialists with this rare and potentially fatal disorder because early recognition of necrolytic migratory erythema, a clinical feature that may appear in patients with glucagonoma, can lead to possible cure, whereas delayed identification of the disease is associated with metastatic disease and a poor prognosis.

Background: In treated facial melanomas, the safety margins generally applied in other body sites cannot be achieved for functional and esthetical reasons. To date there are no controlled studies on safety margins for facial melanomas. Clinical parameters and surgical strategies influencing the prognosis of patients with a facial melanoma were evaluated in a retrospective study of melanoma patients in the Department of Dermatology of the University of Tuebingen (1980-1999).
View Article and Find Full Text PDFFour distinctive clinical and histological variants of pyoderma gangrenosum have been proposed: (1) ulcerative, (2) pustular, (3) bullous, and (4) vegetative. The rate of progression and associated systemic diseases, as well as the histopathologic changes, can vary considerably between these clinical variants. A 64-year-old man presented with ulcerative pyoderma gangrenosum associated with renal cell carcinoma and IgA paraproteinemia; he responded to oral thalidomide.
View Article and Find Full Text PDFBackground: Digital image analysis has been introduced into the diagnosis of skin lesions based on dermoscopic pictures.
Objectives: To develop a computer algorithm for the diagnosis of melanocytic lesions and to compare its diagnostic accuracy with the results of established dermoscopic classification rules.
Methods: In the Department of Dermatology, University of Tuebingen, Germany, 837 melanocytic skin lesions were prospectively imaged by a dermoscopy video system in consecutive patients.
Objective: Sentinel lymph node biopsy (SLNB) has been proposed as a minimally invasive procedure for the histopathologic staging of the regional lymph node basin. The aim of this work was to investigate the prognostic value of detection of micrometastasis by SLNB.
Methods: In the period from January 1996 to March 2000, a sentinel lymph node (SLN) was identified in 283 patients at the Department Dermatology, University of Tuebingen.
Background: True local recurrence (LR) means clinically detectable regrowth of parts of the tumour which were not completely excised. In the literature the term 'LR' has been used in a vague and inconsistent manner that may include satellite and in-transit metastasis.
Objective: The aim of this study was to establish clinical, histological and surgical risk factors for the manifestation of LR and to evaluate the prognostic significance of LR.
Introduction: It is still unclear whether sentinel lymph node biopsy (SLNB) has an effect on the survival or recurrence-free survival of patients. It would be necessary to compare patients with SLNB (or with selective lymph node dissection in the case of positive SLNB) and patients without SLNB who received only a close clinical and sonographic follow-up. To date, no results from prospective, randomized studies of SLNB are available.

Neither the malignant nature nor the prognostic significance of circulating cells could be established. To address this question, we analyzed immunomagnetically isolated circulating melanoma cells for chromosomal aberrations and performed a clinical follow-up study of the enrolled patients.

Objectives: To investigate if the dermoscopic classification of atypical naevi is of any value to discriminate benign from malignant melanocytic lesions.
Methods: Consecutive patients (n = 205) were included with 254 suspicious melanocytic lesions, confirmed by histopathology at the Pigmented Lesions Clinic of the Department of Dermatology, University Medical Center, University of Tuebingen, Germany.
Epithelioid hemangioendothelioma is an uncommon malignant vascular tumor usually involving soft tissue and, in rare cases, the skin. Histologically and biologically it is considered to be a borderline neoplasm between an angiolymphoid hyperplasia with eosinophilia and an epithelioid angiosarcoma. Here we describe an 11-year-old girl with a 1-year history of an isolated, spontaneously appearing, painful ulceration on the instep of the right foot.
View Article and Find Full Text PDFA variety of melanoma-associated antigens have been identified that mediate adhesion, growth, proteolysis, and modulation of immune response. However, the mechanisms by which human normal melanocytes become malignant are not clearly understood. Among the most consistent observations is the up-regulation of fibroblast growth factor-2 (FGF-2) and of the adhesion molecules beta3 integrin and Mel-CAM during melanoma progression.

Introduction: The ambulant follow-up is established for early detection of metastases thus improving the survival probability of tumor patients. In spite of the safety aimed at, follow-up also puts a burden on tumor patients and has effects on their quality of life.
Aim: To investigate within the scope of follow-up, to collect data on the psychosocial burden on melanoma patients in relation to the predictors (medical factors, psychological variables, sociodemographic data) in order to define a "burden-risk patient".
Background: The use of dermoscopy (epiluminescence microscopy, surface microscopy, dermatoscopy) improves clinical diagnostic sensitivity by 10% to 27%, particularly achieved by different algorithms or scores.
Objective: We sought to develop a simplified and highly accurate dermoscopic-point list for cutaneous melanocytic lesions.
Method: We studied consecutive patients with suspicious melanocytic lesions, which were excised and histopathologically examined at our institution.
Background: Subungual melanomas represent approximately 2% to 3% of cutaneous melanomas in White populations. Complete or partial amputation proximal to the distal interphalangeal joint of the digits has been suggested. Recently, we introduced for acral melanomas, similar to lentigo maligna melanoma, limited excision and complete histology of excisional margins (three-dimensional histology).
View Article and Find Full Text PDFBackground: Cutaneous melanoma is the most aggressive form of skin carcinoma in humans, frequently with a rapid progression of disease. To detect early developing metastasis, laboratory tests to determine levels of lactate dehydrogenase (LDH) and alkaline phosphatase (AP) form part of the regular follow-up, but often cannot discover recurrent disease at a sufficiently early stage.
Methods: To evaluate the diagnostic accuracy of protein S-100beta (S-100beta), melanoma-inhibitory activity (MIA), LDH, AP, and tyrosinase/MART-1 reverse transcription-polymerase chain reaction (RT-PCR), the authors included 296 consecutive AJCC Stage II or III clinically disease-free melanoma patients.
Purpose: To prospectively examine and evaluate the results of follow-up procedures in a large cohort of cutaneous melanoma patients.
Patients And Methods: This was a prospective study in 2,008 consecutive patients with stage I to IV cutaneous melanoma from 1996 to 1998 on the yield of stage-appropriate follow-up examinations according to the German guidelines. Documentation of patient and follow-up data comprised patient demography, primary tumor specifics, and any clinical and technical examinations performed.
Unlabelled: The term epidermolysis bullosa (EB) encompasses a heterogeneous group of genodermatoses, characterised by fragility and blistering of the skin, often associated with extracutaneous manifestations. The clinical picture comprises severe subtypes with lethal outcome in the first years of life as well as milder subtypes with localised blistering or minimal symptoms confined exclusively to nail or teeth abnormalities. We present the case of a male infant, who was born with a few bullae and rapidly developed extensive blistering of the skin.

Objective: To assess the efficacy of intravenous regional anesthesia (IVRA) for painless treatment of palmar hyperhidrosis with BTX-A compared to topical application of a local anesthetic agent.
