Severe symptomatic hyperparathyroidism-Is it carcinoma?-Case report and literature review.

Parathyroid carcinoma is a rare disease, difficult to diagnose and associated with a poor prognosis. It must be suspected preoperatively, based on clinical and imaging grounds, in order to perform the best surgical option and avoid compromising patient's prognosis.

Miniprobe endoscopic ultrasonography for the diagnosis of colon hemangiolymphangioma.

Hemangiolymphangioma is a very rare benign vascular tumor that affects the gastrointestinal tract in less than 1% of cases. We present the case of an asymptomatic 52-year-old female referred for endoscopic colorectal cancer screening. A sub-epithelial pediculated polypoid lesion in the splenic angle of the colon was identified.

Proximal-type epithelioid sarcoma-unusual presentation: unilateral vulvar mass.

Epithelioid sarcoma of the vulva is a very rare malignant soft tissue tumour, usually initially asymptomatic, which simulates a variety of benign lesions, leading to diagnosis only at later stages. Prognosis is generally poor. We report a case of a 55-year-old postmenopausal woman, who presented with rapid growth of an asymptomatic mass located in the left labia majora.

The patient was referred to our department due to brown macules, papules and patches with a smooth surface and whitish scaling, located in the lower limbs that had appeared two months ago.
