Radiation therapy is frequently associated with a variety of adverse cutaneous effects. Some of these complications, such as radiodermatitis, are well known. However, some other skin reactions, such as radiation-induced lichen planus (LP) as a kind of isoradiotopic response, are rare, less known, and often underrecognized. An isoradiotopic response refers to the appearance of a secondary dermatosis in previously irradiated areas. In an isoradiotopic response, the new skin lesion presents with all the hallmarks of the primary dermatosis; however, the eruption is restricted to the field of radiation therapy. Radiation-induced LP as a kind of isoradiotopic response refers to the appearance of LP lesions in previously irradiated areas. This article presents a narrative review of the current literature about radiation-induced LP cases. The search was conducted on electronic databases, including PubMed, Web of Science, Cochrane, Scopus, Medline, Embase, and Google Scholar with the keywords, “isoradiotopic response,” “isotopic response,” “Koebner phenomenon,” “lichen planus,” “cancer treatment,” “radiotherapy,” and “radiation therapy.” According to the results of this search, there were only nine case reports of radiation-induced LP in the literature. Due to the limited number of articles published in this field, there are important questions, the answers of which are not known yet. By reporting more patients with post-radiation LP, investigators will be able to gather more information about the pathogenesis of the disease and evaluate the significance of different factors in the development of post-radiation LP.

Background: Basal cell carcinoma (BCC) is the most common type of skin malignancy. Hyperthermia is used as adjuvant therapy together with radiotherapy and chemotherapy in the treatment of some cancers. This study aimed to evaluate the efficacy and safety of thermotherapy in the treatment of BCCs.
Methods: This pilot trial was carried out on five patients with nodular or superficial BCCs on the scalp and face.Thermotherapy was done at 50° C for a duration of 30 seconds with a radiofrequency device (Thermomed 1.8 thermosurgery technologies). Thermotherapy treatment was applied only in one session. The first follow-up was one week after the procedure and then every month for six months. The last follow-up was one year after the procedure.
Results: All patients showed clearance of the tumors. Blisters, ulcers, crusts, and necrosis were the side effects, which healed with acceptable degrees of scarring. No recurrence was observed at the end of the study.
Conclusion: Thermotherapy was safe and efficacious for the treatment of BCCs on the scalp and face. It should be considered especially for the low-risk subtypes of this cancer.

Background: Radiation-induced basal cell carcinoma (BCC) can be multiple, large, and recurring, which complicates its treatment in some cases. According to reports on the role of cyclooxygenase 2 (COX2) inhibitors in the treatment or prevention of non-melanoma skin cancers and considering the fact that COX2 expression has not been evaluated in radiation-induced basal cell carcinoma, weset out to assess the expression of COX2 in these lesions. Methods: In this study, COX2 expression was assessed by immunohistochemistry using anti-COX2 antibody on paraffinembedded blocks of 86 patients referred to Emam Reza Hospitalin Mashhad with BCC diagnosis by pathological examination (43 patients with and 43 without a history of radiotherapy) followed by semi-quantitative evaluation of COX2. Results: In our study, COX2 expression score was significantly higher in patients with a history of radiotherapy than those without radiotherapy (P<0.001). No correlation was found between theintensity and percentage of staining with sex, age, site of lesion, recurrence, and pathology of the tumor. Conclusion: Given the higher expression level of COX2 in the radiation-induced BCC patients, the use of COX2 inhibitors in these individuals may be effective in the incidence, recurrence, or treatment of BCC.

Background: Non melanoma skin cancer (NMSC) is the most common cancer worldwide. In most cases, the general outlook is excellent; however, local recurrence or metastasis can occur. In this study, we investigated possible tumor and host characteristics affecting the treatment outcome in our department of radiation oncology.Method: We retrospectively studied cases with non melanoma skin cancer (NMSC) who were consecutively referred to department of radiation oncology in Omid and Ghaem Hospitals between 1997 and 2007. The effect of the patients’ characteristics (age, sex), tumor characteristics (histology, size, location), and treatment modalities on prognosis were evaluated.Result: We studies 426 patients with a median age of 65 (range: 14 to 102) and a male to female ratio of 1.4:1. Pathologic review showed 72% of the patients had basal cell carcinoma (BCC) and 28% had squamous cell carcinoma (SCC) with a 5-year event free survival of 87±3% and 67±8%, respectively (p < 0.001). The local recurrence rate was higher in cases with scalp lesions (35%). The patients who underwent combined modality treatment experienced significantly more instances of failure as compared to those receiving radiotherapy alone (5-year event free survival of 81±6% vs. 84±6%, p=0.04) which reflects the higher number of cases with adverse features including larger lesions and/or a positive surgical margin in this group. Sex, age, and multifocality were not significant predictors of prognosis.Conclusion: SCC histology and scalp location were predictive of higher rates of treatment failure in patients with NMSC. There was no correlation between age, sex, multifocality and overall outcome. The higher rate of recurrence in cases receiving combined modality treatment is most probably due to the high number of tumors with adverse prognostic features in these cases.

Background: Basal cell carcinoma (BCC) is the most common cutaneous malignancy. UV light is an important risk factor for BCC, as well as X-ray and other ionizing radiations. The aim of this study was evaluation and risk factor assessment of BCC cases referred to Razi hospital tumor clinic. Methods: Patients referred from general clinics with skin biopsies consistent with Basal Cell Carcinoma were enrolled. A questionnaire including epidemiologic data, risk factor exposure and specification of skin lesions was completed for each patient. Results: From October 2005 to October 2006, a total of 476 patients with cutaneous malignancy referred to Tumor clinic of Razi hospital. Of them, 367 patients had BCC. 215 were male (58%) and 152 were female (42%). Mean age of patients was 62 (±12.7) and 62 (±13.4) years for men and women, respectively. The most common risk factors for BCC were radiotherapy and chronic sun exposure. The most common tumor sites were scalp, nose and ears. Of different clinico-pathologic types, noduloulcerative type was the most common. Conclusion: It seems that radiotherapy is an important risk factor in Iranian BCC patients and it is useful to have a screening program for case finding and treating patients in early stages.

Cutaneous leishmaniasis (CL) is a parasitic disease, which is hyperendemic in Isfahan, usually caused by L.major and L.tropica. Herein we report a patient with post-mastectomy lymphedema on right upper limb accompanying with the lesions of cutaneous leishmaniasis on the right and left forearms. Following radiotherapy, the lesions on the limb with lymphedema were disseminated. But the lesions on left side showed no change. This finding may be the result of immune disorder due lymphedema and radiotherapy.
