BACKGROUND The coexistence of breast cancer and tuberculosis is very rare. This can create a dilemma in the diagnosis and treatment as there are no pathognomonic symptoms or signs to distinguish both diseases. CASE PRESENTATION A female patient was seen in the breast clinic for a right breast lump. Clinical examination and investigation confirmed cancer(More)
The use of contrast agents (CA) with liver ultrasound (US) has gained recently an established role for the diagnosis of various hepatic diseases due to their safety, high versatility and low costs (contrast-enhanced ultrasound: CEUS). The purpose of this review is to provide a state-of-the-art summary of the available evidence for their use in the(More)
BACKGROUND Metastases to the breast from extramammary tumours are uncommon, and metastatic renal cell carcinoma to the breast is extremely rare. We report a metastasis to the breast from a renal primary with the radiological and histopathological features. CASE PRESENTATION An 81-year-old lady was seen in the breast clinic for a right breast mass after(More)
BACKGROUND Primary cutaneous melanoma of the breast is a very rare tumour, accounting for < 5% of all malignant melanomas. CASE PRESENTATION A young lady was seen in the breast clinic for a skin lesion in the right breast. Clinical examination and investigations confirmed a diagnosis of a primary cutaneous melanoma of the breast. The lesion was excised(More)
INTRODUCTION Sebaceous gland tumours are rare and their presence should be considered as a marker for Muir-Torre Syndrome, alerting to search for an occult malignancy. CASE PRESENTATION A 43-year-old Caucasian female patient underwent excision of a sebaceous cyst. Histopathology confirmed a sebaceous carcinoma. Further investigations revealed multiple(More)
INTRODUCTION Retroperitoneal cysts are uncommon, with an estimated incidence of 1/5750 to 1/250,000. CASE PRESENTATION A male patient was admitted with an abdominal pain, jaundice and fever. Clinical examination and investigations confirmed an idiopathic benign retroperitoneal cyst. He underwent surgery and was discharged after making good recovery. (More)
BACKGROUND The ex vivo porcine liver perfused model isolates the organ from extrinsic regulatory mechanisms, facilitating an improved understanding of the organ physiology and reaction to various conditions. We have assessed the influence of the addition of a porcine kidney to the circuit. METHODS Eight livers were harvested and perfused for 6 hours. In 5(More)
Merkel cell carcinoma is a rare skin neoplasm and has not been reported yet in a male breast. We present a case of 74-year-old patient who was referred to the breast clinic with a lump in his right breast, which led first to the core biopsy followed by radical mastectomy and axillary clearance. The clinical characteristics, gross, microscopic and(More)
The addition of a kidney to the ex vivo liver perfused model may facilitate the circuit homeostatic balance of important biochemical parameters (i.e. pH changes, urea and creatinine, or glucose levels) but might also increase the inflammatory reaction produced. In this study, we compared the production of various cytokines between liver–kidney and(More)
