Abstract
Zusammenfassung
Ziel: Der »sentinel lymph node« (SLN) reflektiert den Befall der nachfolgenden Lymphknoten-Stationen bei Patienten mit malignem Melanom und hat damit eine erhebliche prognostische Bedeutung. Ziel der Studie war die prä- und intraoperative Lokalisierung dieses Lymphknotens mittels Lymphszintigraphie und Sondenmessung. Methoden: 38 Patienten mit malignem Melanom (Tiefenausdehnung >0,75 mm) wurden nach Injektion von 40 MBq 99Tc-Nanocoll szintigraphisch untersucht. Die Position des ersten im Abflußgebiet dargestellten Lymphknotens wurde an der Haut markiert. Unmittelbar danach wurde intraoperativ mittels einer kollimierten Sonde dieser Lymphknoten aufgesucht und nach Ex- stirpation die Aktivität des Knotens und die Restaktivität im Operations- situs gemessen. Ergebnisse: Bei allen Patienten konnte der SLN szintigraphisch lokalisiert und markiert werden. Vor und nach Exstirpation wurde die höchste Aktivität mit der Sonde im markierten Lymphknoten bestimmt. Makroskopisch und im Ultraschall und CT waren alle Lymphknoten unauffällig. Histologisch zeigten acht Patienten eine Metastasierung im lokalisierten Lymphknoten, die bei sieben Patienten eine großzügige Ausräumung des gesamten nachfolgenden Lymphgebietes nach sich zog. Schlußfolgerungen: Die vorgestellte Methode bietet die Möglichkeit, den morphologisch unauffälligen SLN sicher aufzufinden. Die operative Entfernung des diagnostisch erkannten SLN kann eine grundlegende Zäsur in der Therapie des malignen Melanoms bedeuten, da nur bei positivem Befund eine großzügige Lymphknoten-Ausräumung durchgeführt wird. Die kombinierte Lymphszintigraphie mit Sondenmessung beeinflußt entscheidend das therapeutische Vorgehen aufgrund der sicheren Lokalisation des Lymphknotens und ermöglicht hierdurch eine individuelle Therapieplanung.

Abstract
Summary
Aim: The Sentinel Lymph Node (SLN) is of considerable prognostic relevance, because extended lymph node dissection may not be performed in patients presenting with histologically negative SLN. The aim of the present study was to prove the prognostic value of the SLN-concept in these patients. Methods: So far the clinical follow-up of 162 patients with histologically proven malignant melanoma and metastatically uninvolved (negative) SLN was investigated. Histological examination included standard methods (HE-Test) and special histochemical techniques (S-100, HMB-45). All patients underwent clinical examination, ultrasonic diagnosis of the regional lymph nodes, and x-ray of the chest every 3 months. Results: Despite of negative SLN-findings in 8/162 patients metastases of the malignant melanoma were found after a time period of 5-27 months. Three patients presented with recurrence in the previously mapped (negative) SLN-basin. In another case the scintigraphically visualized SLN could not be identified intraoperativelly by means of the hand-held gamma probe. One patient showed intransit-metastases or skin-metastases, respectively; another patient recurred in the scar area. One patient showed hematogenic dissemination (liver) which is not detectable by lymphoscintigraphy; in another patient metastases were found outside the primary lymphatic basin (cervical). Conclusion: In our patient group 4,9% presented with metastases despite negative SLN while published data report up to 11% (observation period 35 months), among them only 3 patients (1,9%) being real concept failures. Our results underline that there is no evidence to change this concept in patients with clinically early stage.

Abstract
Summary
Aim of this study was to localize the sentinel lymph node by lymphoscintigraphy using technetium-99m colloidal rhenium sulphide (Nanocis®), a new commercially available radiopharmaceutical. Due to the manufacturers’ instructions it is licensed for lymphoscintigraphy. Patients, methods: 35 consecutive patients with histologically proved malignant melanoma, but without clinical evidence of metastases, were preoperatively examined by injecting 20-40 MBq Nanocis® with (mean particle size: 100 nm; range: 50-200 nm) intradermally around the lesion. Additionally blue dye was injected intaoperatively. A hand-held gamma probe guided sentinel node biopsy. Results: During surgery, the preoperatively scintigraphically detected sentinel lymph nodes were identified in 34/35 (97%) patients. The number of sentinel nodes per patient ranged from one to four (mean: n = 1.8). Histologically, metastatic involvement of the sentinel lymph node was found in 12/35 (34%) patients; the sentinel lymph node positive-rate (14/63 SLN) was 22%. Thus, it is comparable to the findings of SLN-mapping using other technetium-99m-labeled nanocolloides. Conclusion: 99mTc-bound colloidal rhenium sulphide is also suitable for sentinel node mapping.

Abstract
Congenital melanocytic nevi are rare lesions which depending on their size and location may cause major cosmetic and psychological problems. Large congenital melanocytic nevi may undergo malignant change and can also be associated with neurocutaneous melanosis. The different treatment approaches reach different levels of the skin. Complete excision is the treatment of choice, but is not always possible with giant nevi. Superficial treatment can reduce the pigmentation, but repigmentation is not uncommon. Incomplete removal of melanocytic nevi does not reduce the melanoma risk. Surgical intervention must be carefully planned; the advantages and disadvantages of the different modalities must be discussed with the parents. The risk of malignant transformation must be weighed up against the expected aesthetic and functional outcomes.

Abstract
The incidence of the most common tumors of the skin, basal cell carcinoma and squamous cell carcinoma, has risen rapidly in recent years. Dermatologists see in their daily practice many different clinical and histological variants of these tumors. They must be able to develop therapeutic strategies adapted to the tumor and the patient. Surgical excision remains the standard treatment. Micrographic histological evaluation should be employed in difficult locations, for large tumors and when there is increased risk of recurrence or metastasis. For initial or superficial lesions, other approaches such as radiation therapy, as well as curettage, cryosurgery, laser therapy and photodynamic therapy can be employed. An additional option is topical treatment with imiquimod or 5-flourouracil.

Abstract
INTRODUCTION Facial lipoatrophy is a crucial problem of HIV-infected patients undergoing highly active antiretroviral therapy (HAART). Poly-L-lactic acid (PLA), provided as New-Fill/Sculptra, is known as one possible treatment option. In 2004 PLA was approved by the FDA as Sculptra for the treatment of lipoatrophy of the face in HIV-infected patients. While the first trials demonstrated relevant efficacy, this was to some extent linked to unwanted effects. As the depth of injection was considered relevant in this context, the application modalities of the preparation were changed. The preparation was to be injected more deeply into subcutaneous tissue, after increased dilution. MATERIAL AND METHODS To test this approach we performed a pilot study following the new recommendations in 14 patients. RESULTS While the efficacy turned out to be about the same, tolerability was markedly improved. The increase in facial dermal thickness was particularly obvious in those patients who had suffered from lipoatrophy for a comparatively small period of time. CONCLUSION With the new recommendations to dilute PLA powder and to inject it into the deeper subcutaneous tissue nodule formation is a minor problem. However, good treatment results can only be achieved if lipoatrophy is not too intense; treatment intervals should be about 2-3 weeks.

Abstract
Early versus delayed excision of lymph node metastases is still being assessed in malignant melanoma. In the present retrospective, multicentre study, the outcome of 314 patients with positive sentinel lymphonodectomy (SLNE) was compared with the outcome of 623 patients with delayed lymph node dissection (DLND) of clinically enlarged lymph node metastases. In order to avoid the lead-time bias, survival was generally calculated from the excision of the primary tumour. Survival curves were constructed using the Kaplan-Meier product-limit estimate. Cox's proportional hazards model was used to perform a multivariate analysis of factors related to overall survival. Compared with SLNE and early performed complete lymph node dissection, DLND yielded a significantly higher number of lymph node metastases. Median and mean tumour thickness were nearly identical in the two therapy groups. The estimated 3-year overall survival rate was 80.1+/-2.8% (+/-standard error of the mean (SEM)) in patients with positive SLNs, and 67.6+/-1.9% in patients with DLND (5-year survival rates 62.5+/-5.5 and 50.2+/-5.4%, respectively). The difference between the two survival curves was statistically significant (P=0.002). Using multifactorial analysis, SLNE (P=0.000052), American Joint Committee on Cancer (AJCC) Breslow thickness category (P<0.000001), age (P=0.01) and gender (P=0.028) were independent predictors of overall survival. The location of the primary tumour (P=0.59) was non-significant. Considering only those centres with sufficient data for epidermal ulceration, this risk factor was also significant. In cutaneous malignant melanoma, early excision of lymphatic metastases, directed by the sentinel node procedure, provides a highly significant overall survival benefit.

Abstract
Analysis of data of 6298 patients with cutaneous melanoma seen at the Department of Dermatology and Allergology at the Ludwig-Maximilians University of Munich between 1977 and 1998 identified 31 patients who first experienced metastatic disease 10 or more years after surgical treatment of the primary melanoma. The mean tumor thickness in patients with late progression of disease was 1.4 mm. There was no sex predominance. Of 31 patients, 15 (48. 3%) were female and included both premenopausal and postmenopausal women at the time of initial diagnosis without any predominance. Sixteen of the 31 patients (51.6%) with late onset of progression had primary tumors located on the trunk. The prognosis after relapse was related to the site of recurrence; survival after local or regional node recurrence was often prolonged, whereas survival after distant metastases usually was limited. Survival after late recurrence did not correlate with disease-free survival. A high-risk group for late recurrence could not be identified. The data emphasize the value of continued clinical follow-up and self-examination for early detection of regional recurrences. We advocate a lifelong follow-up, also to identify other melanocytic lesions at risk (eg, dysplastic nevi, secondary or multiple melanomas).

Abstract
Between 1987 and 1998, 64 patients with lentigo maligna (LM) (n = 42) or lentigo maligna melanoma (LMM) (n = 22) were treated by fractionated radiotherapy. In all 22 patients with LMM, excision of the nodular part of the LMM was performed before radiation of the residual lentiginous tumor. During the follow-up period of 1 to 96 months (mean, 23 months; median, 15 months), none of the 42 patients with LM displayed any signs of recurrence of LM after radiation therapy alone. Of the 22 patients with LMM, only 2 patients showed local recurrence of the tumor, salvaged by excision in both cases. One patient with LMM suffered from metastatic disease without local recurrence of the melanoma 44 months after radiation therapy. The cosmetic results of radiotherapy were good or excellent in the vast majority of patients, with only a few experiencing hypopigmentation or hyperpigmentation in the irradiated area. Fractionated radiation therapy with superficial x-rays is an effective method of treatment of LM associated with low morbidity and leading to clinical results comparable to those of surgical excision.

Abstract
BACKGROUND AND OBJECTIVE Lipomas should be included in the differential diagnosis of tumors located on the forehead. They require a different operative plan. PATIENTS/METHODS Lipomas of the forehead were extirpated in ten patients. Dermatohistopathologic investigations confirmed the diagnosis lipoma in each case and exactly identified the anatomic layers surrounding the tumor. RESULTS Histologic investigations revealed the localization of the lipoma in the submuscular layer in eight patients and in the subgaleal layer in two patients. CONCLUSIONS Lipomas of the forehead should be differentiated into submuscular and subgaleal lipomas depending on the exact anatomic localization below the frontalis muscle or underneath the galea aponeurotica. This classification is simple and aids in operative planning.

Abstract
Since 1997, data of patients with malignant melanomas have been systematically documented in the tumor registry of the Tumor Center Munich. Analysis of data of 8071 patients revealed that tumor thickness has steadily declined over the years. While in 1977 the median tumor thickness was 1.45 mm, it is now 0.75 mm. This has been followed by a significant improvement in overall survival. Males and older patients tend to have thicker melanomas than females and younger patients. There has been a relative increase of melanomas of the trunk. At diagnosis, 95% of patients had local disease. Of these patients, 18.3% developed metastastes. At least two-thirds of these patients had progression at the primary tumor site or the regional lymph nodes, both of which can be assessed by clinical or ultrasound examinations. Overall survival of patients with thin melanomas is excellent and does not differ substantially from the overall survival of the general population comparable in sex and age.

Abstract
Small basal cell carcinomas of the trunk are usually regarded as relatively harmless. In contrast, large and ulcerating basal cell carcinomas may become a therapeutic challenge with a less favourable prognosis and high risk of recurrence. The development of mutilating giant basal cell carcinomas appears less due to the biological aggressive character of the tumors, but rather to the patients' attitude of neglect. The case of a 62-year-old patient, featuring such attitude, demonstrates how a common basal cell carcinoma of the trunk can grow over a period of years to a troublesome ulcerating tumor.

Abstract
AIM The sentinel lymph node (SLN) has shown to reflect the histologic features of the remainder of the lymphatic basin in patients with melanoma and is of considerable prognostic relevance. Aim of the study was to localize the SLN pre and intraoperatively by means of lymphoscintigraphy and gamma probe guidance. METHODS 38 patients with histologically proven malignant melanoma (tumor thickness > 0.75 mm) were preoperatively examined by injecting 40 MBq 99mTc-Nanocoll intradermally around the lesion. The first lymph node identified was marked on the skin. Immediately after scintigraphy patients were referred to the operation room and intraoperatively mapped using a handheld gamma probe. Activity of the SLN and of the adjacent nodes was measured ex vivo. After excision of the SLN, the lymphatic basin was re-checked for radioactivity and activity of the SLN and of the adjacent nodes was re-measured after removal. RESULTS The hottest reading was found in all patients in vivo and ex vivo in the preoperatively marked lymph node. Morphologically (macroscopically, ultrasound, CT) all nodes were unsuspicious. Histologically, in 8 patients metastatic involvement of the lymph node was found which led to a wide exploration of the lymphatic basin with consecutive lymph node excision in 7 patients. CONCLUSION The findings suggest that combined preoperative lymphoscintigraphy and intraoperative mapping with a gamma probe is a powerful approach for exact localization of the SLN. Diagnostic detection of the SLN may have considerable impact for patient management, since extended lymph node dissection may be confined to patients presenting with positive SLN.

Surgical reconstruction of the nasal skin resulted in an excellent and long lasting effect. We give a short overview of this relatively rare disease, describe an unusual manifestation and discuss the therapeutic possibilities. Surgical procedures seem to offer the best results, despite the inflammatory pathogenesis of the disease.

Pyoderma gangrenosum associated with secondary antiphospholipid syndrome was diagnosed based upon the typical clinical features and increased antibodies to cardiolipin. Although an aggressive therapy with corticosteroids and cyclosporine was started, her condition continued to worsen. She finally died as a result of sepsis. We discuss the difficulties in diagnosis and therapy of SLE combined with the antiphospholipid syndrome and pyoderma gangrenosum.

Abstract
Micrographic surgery is one of the most effective methods in the treatment of basal cell carcinoma. In the last 20 years this method has been further developed and modified. Three kinds of micrographic surgery are now available: the Mohs method, the margin strip method ("Tübingen torte") and the "Munich" method. All three variants have the same goal; radical tumour removal with optimal sparing of surrounding tumour-free tissue. They differ, however, in the technique of tumour excision, the preparation of the histological specimens and the interpretation of the slides. In this paper the authors take stock of the methods available and describe the differences, advantages and disadvantages.

Abstract
The appearance of severe ulceration of the skin in patients with rheumatoid arthritis is often associated with a tendency to progression of the underlying disease, involvement of internal organs and increased mortality. In the pathogenesis of such ulceration there are multiple causes for their development, persistence and tendency to poor healing. They include localized or generalized immune complex vasculitis, treatment with anti-inflammatory drugs and their side effects following the treatment, arterial and venous insufficiency, and mechanical factors. The management of severe ulceration requires stabilization of the underlying autoimmune disease, e.g. with high doses of glucocorticosteroids or other immunosuppressive drugs or plasmapheresis. Adjuvant treatment of pain with analgesics, improvement of blood perfusion and anti-inflammatory drugs should accompany the topical therapy of ulcers. After suppression of the local inflammatory reaction surgical intervention becomes necessary in most of the patients, and vascularized muscle flaps should be used in preference to meshgrafts or split skin grafts for extensive ulceration in rheumatoid arthritis. A hopeful perspective in the treatment of severe rheumatoid arthritis might be opened up with immunotherapy using monoclonal antibodies.

Abstract
BACKGROUND AND OBJECTIVE The treatment of epidermal nevi is difficult and often unsatisfactory. Many therapeutic approaches have been tried, of which the surgical methods including lasers aim to avoid recurrences and hypertrophic scarring. Here we report the case of a widespread, life-impairing epidermal nevus, summarize the available treatment modalities, and discuss CO2 laser therapy with respect to the clinically soft variants of these developmental defects. STUDY DESIGN/PATIENTS AND METHODS A patient with a widespread, recurrent, biopsy-proven epidermal nevus was treated with a 10,600-nm CO2 laser. After test treatments in local anaesthesia, four sessions were performed under general anaesthesia each with a follow-up time of 4 years to date. RESULTS CO2 laser vaporization resulted in complete removal of the treated nevus without any obvious scarring. The patient is free of recurrence 4 years postoperatively. CONCLUSION CO2 laser treatment of epidermal nevi is a useful modality in selected variants.

Abstract
BACKGROUND The hazards of acute radiation exposure are well known. Bone marrow failure from total body gamma or neutron irradiation is the most clinically relevant aspect of acute radiation disease. With nonhomogeneous exposure, as is characteristic in accidents, other organ systems, such as the skin, may be more important in determining clinical prognosis. This became obvious in the two worst radiation accidents since 1945, the Chernobyl accident in April 1986 and the Goiania accident in September 1987. OBJECTIVE Our purpose was to describe the characteristic chronic sequelae of accidental cutaneous radiation in a group of patients who survived the Chernobyl nuclear power plant accident. METHODS Fifteen patients with the delayed type of the cutaneous radiation syndrome were examined between September 1991 and January 1992. All patients had a history of acute radiation disease. The exposure pattern was characterized by partial body exposure with high doses of beta and gamma irradiation from radioactive water, steam, or dust. RESULTS Radiation-induced lesions were confined primarily to the legs and distal arms, but sometimes involved up to 50% of the total body surface. In addition to telangiectases, radiation keratoses, and radiation ulcers, hemangiomas, hematolymphangiomas, splinter hemorrhages in the distal nail bed, lentiginous hyperpigmentation, and severe subcutaneous fibrosis were noted. No malignant transformation could be detected. Associated diseases included cataracts, chronic hepatitis, and recalcitrant bacterial and herpesvirus infections. CONCLUSION After accidental partial body exposure to high doses of beta and gamma irradiation, the predominant involvement of the skin, described as the cutaneous radiation syndrome, can become the characteristic feature. This causes longlasting, serious diagnostic and therapeutic problems.

Abstract
The five-year disease-free rate (5-y-DFR) and five-year survival rate (5-y-SR) of 319 melanoma patients with a narrow excisional biopsy in local anesthesia as the first procedure followed by delayed wide excision, were compared with 5-y-DFR and 5-y-SR of 635 primary radically treated patients. Five-y-DFR and 5-y-SR did not differ in either group of patients. Furthermore, the time interval (less than or equal to 21 days versus greater than 21 days) between excisional biopsy and delayed wide excision had no influence on the outcome of the patients. Based on the results of the study and the literature, excisional biopsy of malignant melanoma followed by delayed wide excision is a safe procedure.

Abstract
Immunochemotherapy combining dacarbazine with BCG is a possible therapeutic method for the adjuvant treatment of malignant melanomas. The routes of application of BCG, however, vary. As the case of a 61-year-old female shows, subcutaneous injection can lead to severe ulcerations, which respond to tuberculostatic therapy. Therefore scarifications seems to be preferable.

Abstract
Since 1967 a total of 2403 patients with malignant melanoma have been treated according to a standardized regimen. The five-year survival rate for all patients in stage I was 79%. It was clearly dependent on tumour thickness or prognostic index, respectively. If tumour thickness was less than 0.75 mm or the prognostic index under 6, more than 90% survived for five years. With a tumour thickness of more than 3 mm or a prognostic index of greater than 13 the survival rate decreased to about 50%. Irrespective of tumour thickness the first signs of progression were local recurrence (20%), lymph-node metastases (50%), or distal metastases (30%). In case of progression symptoms recurred in about 80% within the first three years after tumour removal, in about 90% within five years. However, some 10% of progression signs occurred after more than five years. Prognosis was not significantly improved in stage I by adjuvant treatment with dacarbazine and BCG. In stage II the five-year survival rate was still about 30%. But in stage III only those patients with exclusively cutaneous distal metastases had a somewhat better prognosis. Only a few patients lived more than three years after the occurrence of organ metastases.

Abstract
Within 24 h of intracutaneous administration of an injectable collagen implant, a 34-year-old woman developed reddish-yellow nodules at two test implantation sites as well as at treatment sites. These nodules have persisted for more than 8 months. Histological findings seem to be consistent with an allergic reaction of the granulomatous type (type V).

Abstract
We report on a 72 years old man showing a strikingly fast spreading malignant melanoma developing on a lupus vulgaris which had existed since childhood. The coincidence of both diseases is obviously extremely rare. A pathogenetic relationship between melanoma and lupus vulgaris, such as claimed for carcinoma in lupo, especially after X-ray irradiation, is not inferable.

Abstract
Congenital giant nevi are rare. There is high risk of malignant melanoma in large congenital nevi. Therefore the early operative removal is advised, not only for the prevention of malignant tumors, but also for psychologic and social reasons. The surgical and reconstructive methods include serial excisions, free skin-grafts and local pedicled flaps. The special advantages of free full-thickness grafts in the treatment of giant nevi in the facial region are outline.

Abstract
Different motivations are seen in patients with tattoos, which can be seen in a tattooed picture. Two kinds of tattoos can be distinguished: Professional and self-made tattoos. In general, patients with self-made tattoos call for their removal, because the private situation has changed. These tattoos are more difficult in treatment than professional ones, because the colour is located in the whole dermis. The method of treatment depends on size, form and shape of the tattoo. For treatment simple excision of small tattoos, dermabrasion in one or two sessions are recommended. Own experiences and results in 121 patients with tattoos are reported and discussed.

Abstract
The coincidence of cyclindromas and trichoepitheliomas has been subject of a rather broad discussion for its principal pathogenetic aspects. Clinical cases, however, have only rarely been observed. Therefore, a case-report is given. Although the heredity of the Brooke-Spiegler syndrome seems well established by now, there is no anamnestic data in our case.

Abstract
Although cryostat sections in general allow a distinction to be made between malignant melanomas and other pigmented lesions in clinically doubtful cases, the differential diagnosis may be difficult. The histological and cytological criteria taken into account can be classified as major, minor, and insufficient. Knowing the diagnostic value of each makes a conventionally established diagnosis safer. Variance analysis does not contribute to the problem but it can nevertheless be shown that the evaluation of six major criteria makes a quick and reliable cryostat section diagnosis possible. If these results are confirmed in a prospective study it would be a decisive step on the way to a quicker and safer cryostat section diagnosis of malignant melanoma, even for the less experienced histopathologist.

Abstract
In 233 (40.6%) of 535 patients referred for hospital treatment with a strong suspicion of melanoma, a diagnosis of malignant melanoma could be established on the grounds of the macroscopic clinical picture alone. In 302 patients (56.5%) a clinical diagnosis was not possible so that an intra-operative cryostatic section investigation was necessary to determine future operative measures. This gave a clear diagnosis of malignant melanoma in 101 (34.4%) patients and a benign pigmented skin tumor was established in 171 (56.6%) patients. In 14 cases (4.64%) no diagnosis could be made from the cryostatic investigation. In 16 (5.3%) patients diagnosis from cryostatic section had to be corrected after analysis of paraffin sections. Altogether an accuracy of over 85% was achieved.

Abstract
Superficial basal cell carcinomas of the trunk may be removed by dermatome excision. The procedure following the usual excision of a split-skin graft with a thickness of 0,6 mm. Histological control of the tumor excision is possible when the split-skin graft, including the tumor, is rolled before sectioning. In this way the adequate tumor removal, both in depth and at the peripheral margin, can be judged.

Abstract
Different flap techniques for plastic repair of defects are described, namely, local flaps (advancement, transposition and rotation flaps) and regional flaps. Such use of skin of similar structure and pigmentation gives excellent cosmetic results. The indications for using local or regional flaps depends on size and location of the defect. Total extirpation of cutaneous malignancy particularly by microscopically monitored serial excision is a prerequisite to reconstruction.

Abstract
In 72 basal-cell epitheliomas, the clinical extension and the actual extension of the defect measured by complete tumor removal by Mohs' chemosurgery were compared. Subclinical extension depends on the type of basal-cell epithelioma (primary, recurrent), on case history, location, clinical diameter, number of previous treatments and histological type. It is remarkably great in large (diameter more than 20 mm), in morphea-like basal-cell epitheliomas on the forehead, temple and scalp, especially following several previous treatments. In such cases the excision should include at least a 5-10 mm margin of "normal tissue." Present results again show that "histographic," that is, Mohs' chemosurgery is the method of choice for the treatment for these tumors.
