BACKGROUND: Cutaneous adverse events associated with the use of epidermal growth factor receptor inhibitors, such as cetuximab are relatively common. Although there are reports about possible treatments for acne or acneiform lesions induced by cetuximab, there are only few reports of prospective studies. OBJECTIVE: The aim of the study was to analyze the efficacy of varius treatment modalities and their combinations in patients with acneiform eruptions caused by cetuximab. PATIENTS AND METHODS: We studied 14 patients treated with an epidermal growth factor receptor inhibitors, including 7 patients cetuximab, who developed acneiform eruptions in the course of therapy. All patients were diagnosed as grade II according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. A corticosteroid ointment, tacrolimus ointment, and ketoconazole ointment were used in a randomized manner. Oral therapy included administration of antihistaminic drugs, tetracycline, a cyclooxygenase inhibitor, or a macrolide. We measured the numer of days required to achieve improvement from grade II to grade I during cetuximab treatment. RESULTS: Our results showed that tetracycline treatment may shorten the period needed to achieve improvement. Ketoconazole cream and a combination of oral tetracycline and topical ketoconazole also significantly shortened this period. CONCLUSION: The results of our short case study may indicate that a combitation therapy of oral tetracyclin and topical ketokonazole is most effective in the therapy of patients with acneiform eruptions caused by cetuximab.
ABSTRACT
INTRODUCTION: Myocardial sarcoidosis is known as a significant complication of sarcoidosis, but Holter electrocardiographic monitoring or echocardiograms might not be sensitive enough to detect cardiac involvement. While gallium scintigraphy has been recommended, 18F-fluorodeoxyglucose positron emission tomography-computed tomography might be more sensitive to detect sarcoidosis. CASE PRESENTATIONS: This report comprises the cases of 12 Japanese patients. Two were male, and ten were female. Their age range was between 32 and 93 years. The average age of the patients was 63. We found internal involvement of sarcoidosis in eight (89%) of nine patients by positron emission tomography-computed tomography and in two (67%) of three patients by gallium scintigraphy. Myocardial sarcoidosis was detected in four (33%) of twelve patients, and specifically in three (75%) of four facial multiple plaque type sarcoidosis patients. CONCLUSION: The myocardial lesions detected by positron emission tomography-computed tomography could not be detected with conventional electrocardiogram or echogram. Positron emission tomography-computed tomography can detect sarcoid lesions of the whole body and is useful for the follow up of patients. We recommend positron emission tomography-computed tomography for those patients having cutaneous sarcoidosis, especially facial multiple plaque type sarcoidosis.

Although ciclosporin is useful for atopic dermatitis (AD), appropriate dosage and therapeutic drug monitoring (TDM) has been performed only by post-prandial ciclosporin administration. We administered ciclosporin pre-prandially to eight severe adult AD patients (four cases of erythrodermic AD, three cases of AD recalcitrant to standard therapy, and one AD case with numerous pruriginous lesions). Blood concentrations of ciclosporin at various dosages were measured and appropriate dosage in terms of therapeutic efficacy was analyzed by using the area under the concentration curve (AUC). AUC was estimated by the C1 (obtained serum concentration of ciclosporin at 1 hour after ciclosporin administration), C2 (concentration of ciclosporin at 2 hours) and C4 (concentration of ciclosporin at 4 hours) concentrations of ciclosporin. The trough levels of ciclosporin with 200 mg/day, 150 mg/day, and 100 mg/day administration were 96.5 ng/ml, 66.4 ng/ml, and 75.3 ng/ml, respectively. The peak serum concentration (C(max)) was obtained at 1 hour (C1) in most cases. The AUC of 0-4 hours (AUC 0-4) were 2099.5 ng · h/ml (200 mg/day), 1782.6 ng · h/ml (150 mg/day) and 1696.2 ng · h/ml (100 mg/day). VAS scores of itching and blood eosinophil counts were decreased significantly by the ciclosporin treatment. Pre-prandial administration of a relatively low dose of ciclosporin for severe atopic dermatitis resulted in a favorable subjective and objective clinical response and the measurement of blood concentration mostly correlated with the effective dosage assessment.

We describe 2 cases of male nipple leiomyoma. A 70-year-old man had a painful subcutaneous tumor on his left nipple of 6 months duration. Histopathology disclosed dermal spindle cells with oval-shaped nuclei forming interlacing bundles with irregular pattern. Glandular elements were absent. The spindle cells were positive to α-smooth muscle actin, desmin, and vimentin. Estrogen receptor (ER) and progesterone receptor (PrR) were negative. We diagnosed this case as male leiomyoma of the nipple. Another patient was a 61-year-old man with gynecomastia induced by spironolactone of 6 months duration. He also had a painful nodule on his left nipple and histopathology disclosed spindle-shaped tumor cells as in the previous patient. The tumor was accompanied by glandular elements in the deep dermis and subcutaneous tissue, which showed apocrine secretion and were positive for α-smooth muscle actin, ER, and PrR. These glandular elements were interpreted as mammary gland. But ER and PrR stain did not show positive results for leiomyoma in the upper dermis. To the best of our knowledge, this is the first report of male idiopathic and gynecomastia-induced leiomyoma with ER and PrR staining.
