Fibroadenomas are the most common breast disease that occurs usually in young. The coexistence of an invasive ductal carcinoma and a fibroadenoma in the ipsilateral breast is extremely rare. We present the case of a 52 years woman, presented to us for an upper-outer breast lump. Breast imaging concluded to tow contiguous lesions, one of them was suspicious. She had a conservative surgery. Histology concluded to a fibroadenoma and an invasive ductal carcinoma.

Merkel cell carcinoma (MCC) is a rare malignant neuroendocrine tumor more common in immunosuppressed old patients. It is characterized by a high frequency of local recurrence, regional nodal metastasis, distant metastasis, and low survival rate. The diagnosis of MCC is challenging due to its rarity and can be clinically mistaken for other skin cancer. We report a case of locally advanced MCC of the left groin with aggressive behavior that was finally controlled with a combined treatment and we collected data from the literature to discuss the appropriate therapeutic algorithm for the management of this uncommon skin tumor.

Cutaneous leiomyosarcoma is a rare soft tissue sarcoma. We present a case of a 50-year-old man, with a rare location in the flank. Clinical presentation showed an ulcerative lesion. Imaging features were evocative of malignancy. Surgical excision was performed, involving oblique muscles. The diagnosis of low-grade leiomyosarcoma with free margins was made. No adjuvant therapy was indicated. Clinical and radiological follow-up of the patient during two years did not reveal recurrences. Cutaneous leiomyosarcoma of the flank is extremely rare and takes part in a group of infrequent and unknown tumors. Clinical presentation is unspecific and histological evidence is mandatory for diagnosis. Tumor extension in depth constitutes the major determinant factor for therapeutic management and prognosis. Wide surgical resection is crucial to minimize recurrence risk especially when poor prognostic factors take place. Ó 2014 Production and hosting by Elsevier B.V. on behalf of King Saud University.
