Breast metastasis in a young pregnant woman affected by metastatic melanoma.

Metastasis to the breast from extramammary tumors are rare, and the most common cancer that metastasizes to this site is malignant melanoma (MM). Unfortunately, metastases from malignant melanoma reveal a widespread of the disease and a high likeliness of poor diagnosis. In this study, a case of left breast metastasis of MM in a young pregnant woman, with a fast progression of the mammary and systemic course of pathology and unfortunately poor prognosis is presented. Despite the role of pregnancy in MM has yet to be unraveled, our study encourages the theory that immunosuppression and hormonal changes due to pregnancy may aggravate melanoma prognosis.

Castleman disease: a rare case in a young woman.

Castleman disease is a rare lymphoproliferative disorder characterized by benign enlargement of lymph nodes. It is divided into unicentric disease, which involves a single enlarged lymph node, and multicentric disease, which affects multiple lymph node stations. In this report, we describe a rare case of a 28-year-old female patient with an unicentric Castleman disease. Computed tomography and magnetic resonance imaging revealed a well-circumscribed large mass in the left neck, characterized by intense homogenous enhancement and suspected for a malignant disease. The patient underwent an excisional biopsy for definitive diagnosis of unicentric Castleman disease and ruled out malignant conditions.

Abdominal Lymphadenopathies: Lymphoma, Brucellosis or Tuberculosis? Multidisciplinary Approach-Case Report and Review of the Literature.

Abdominal pain represents a frequent symptom for referral to emergency departments and/or internal medicine outpatient setting. Similarly, fever, fatigue and weight loss are non-specific manifestations of disease. The present case describes the diagnostic process in a patient with abdominal pain and a palpable abdominal mass. Abdominal ultrasonography confirmed the presence of a mass in the mesogastrium. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) scans oriented toward calcific lymphadenopathies with increased metabolism in the positron emission tomography-computed tomography (PET-CT) scan. Laboratory examinations were inconclusive, although serology for Brucella and the Quantiferon test were positive. After multidisciplinary discussion, the patient underwent surgical excision of the abdominal mass. Histological examination excluded malignancies and oriented toward brucellosis in a patient with latent tuberculosis. The patient was treated with rifampin 600 mg qd and doxycycline 100 mg bid for 6 weeks with resolution of the symptoms. In addition, rifampin was continued for a total of 6 months in order to treat latent tuberculosis. This case underlines the need for a multidisciplinary approach in the diagnostic approach to abdominal lymphadenopathies.

Twig-like middle cerebral artery in a case of neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder with multisystemic involvement, affecting central nervous system, skin, bone system and vessels, with a very heterogeneous clinical presentation. Vascular abnormalities are typically recognized in neurofibromatosis type 1 affecting cardiovascular and cerebrovascular systems. The incidence of circle of Willis anomalies in children with NF1 is twofold higher than in general population. In this paper, we report of 19-years-old female with NF1 and twig-like middle cerebral artery.
