Metastatic sebaceous cell carcinoma, review of the literature and use of electrochemotherapy as possible new treatment modality

Metastatic extraorbital sebaceous carcinoma is a rare event that could involve the head and neck. The treatment of choice for the initial stage of the disease is surgery and/or radiotherapy. The treatment of recurrent or advanced disease is still controversial

Sentinel lymph node biopsy in cutaneous melanoma

The management of melanoma is constantly evolving. New therapies and surgical advances have changed the landscape over the last years. Since being introcuced by Dr Donald Morton, the role of sentinel lymph node has been debated. In many melanoma centres, sentinel node biopsy is not a standard of care for melanoma above 1 mm in thickness. The results of the MSLT-II trial are not available for a while and in the meantime, this procedure is offered as a prognostic indicator as it has been shown to be very useful for assessing risk of relapse. The biology of lymph node spread in melanoma is a complex field and there are many factors which influence it such as age, melanoma body site, thickness but other factors such as regression, ulceration and gender need further evaluation

Metastatic sebaceous cell carcinoma, review of the literature and use of electrochemotherapy as possible new treatment modality

Background. Metastatic extraorbital sebaceous carcinoma is a rare event that could involve the head and neck. The treatment of choice for the initial stage of the disease is surgery and/or radiotherapy. The treatment of recurrent or advanced disease is still controversial. Material and methods. Extensive literature search was done, and the treatment options are discussed. Results. Results. The literature search found several treatment modalities in use for the treatment of metastatic extraorbital sebaceous carcinoma. Electrochemotherapy was not included in the reported treatments. We used this technique for a man of 85 years old with a recurrent and locally metastatic extraorbital sebaceous carcinoma of the scalp. During the period of 8 months, two sessions of electrochemotherapy were employed, which resulted in an objective response of the tumour and good quality of life. Conclusions. Electrochemotherapy has shown to be a interesting tools for treatment of metastatic extraorbital sebaceous carcinoma when other radical options are not available or convenient

Prognostic role of histological regression in cutaneous melanoma

Histological regression in primary cutaneous melanoma occurs in 10-35% of cases. Although there is a large body of literature on histological regression and prognosis in melanoma patients, not clear data concerning this feature has been reported. In the current review, a comprehensive overview of the main aspects of regression will be provided. The clinical utility of regression as a prognostic factor has been challenged recently. Nowadays evidences reported that this feature is protective on SLN metastases. Despite its association with poor prognostic factors, it maintained a favourable prognostic role in many different survival studies
