Lymphoepithelioma-like carcinoma of the breast is uncommon with only 21 patients documented in the literature. It can wrongly be diagnosed as medullary carcinoma and certain types of lymphoma due to undifferentiated proliferation of malignant epithelial cells with prominent lymphoid infiltration. In this paper, we present a case of LELC of the breast in a 64-year-old female with breast LELC and a discussion based on a review of the literature.

Penile calciphylaxis is a rare and highly morbid condition mainly affecting diabetic patients with chronic renal failure (CRF). It is characterized by ischemic skin ulceration and necrosis secondary to dystrophic calcification of the subcutaneous penile tissue and penile arterioles. We report a 52-year-old male with a 6-year history of diabetes mellitus and CRF on hemodialysis, who presented with a painful penile necrotic lesion in the last three weeks. He firstly treated with medical treatment, which was failed. Then underwent total penectomy. The histopathology result confirmed the diagnosis of penile calciphylaxis. Unfortunately, he passed away due to septic shock and multisystem organ failure ten days after surgery. In conclusion, the diagnosis of penile calciphylaxis must be evoked in the presence of any minimal necrotic penile lesion in a patient with CRF; this will initiate quick medical and/or minimally invasive surgical treatment to improve the patient's prognosis and avoid serious complications.

Trichoblastoma is a rare benign skin adnexal tumour, belonging to the category of trichogenic tumours. The clinical and histological findings may often be confused with basal cell carcinoma, a malignant epidermal skin tumour.We report here a case of a 70-year-old man presented with a dome-shaped, dark-pigmented nodule within a yellowish hairless plaque on the scalp. The plaque had existed since childhood. However, the central pigmented nodule began appearing three months ago and enlarging gradually. The patient had no medical history. Furthermore the physical examination revealed a translucent, verrucous, and yellowish plaque, with central and pigmented nodule measuring 0.7 × 0.5 cm. Also basal cell carcinoma and trichoblastoma's diagnosis were discussed. The patient was subsequently referred to the plastic surgery department, where he underwent a total excision. The histological examination was in favour of trichoblastoma arising from the nevus sebaceus. After 24 months of checking, no recurrence was observed.Trichoblastoma is a benign adnexal tumour. Its progression to malignant trichoblastoma (or trichoblastic carcinoma) is possible, but remains exceptional. Therefore, complete excision should be proposed to the patient at the time of diagnosis.
