A Road From Coronary To Pulmonary: A Rare Imaging Presentation

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Its association with Pulmonary Atresia is considered to be the most severe form, the diagnosis of which plays an import ant role in determination of the treatment protocol. In such cases, systemic vascular channels called Major Aortopulmonary Collat eral Arteries (MAPCA’s) develop from aorta and its major branch es to supply and maintain the pulmonary circulation. Such patients commonly undergo a Cardiac CT as an imperative pre-operative investigation for detailed information of these collaterals which helps plan further management.

SARS-Cov2 and limb ischemia

Patients with severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) infection mainly present severe pneumonia associ ated with complications related to cytokine storm syndrome. So, it was associated with thrombotic incidents like acute limb ischemia and pulmonary embolism.

A metastatic melanoma patient with spontaneous melano-ma-associated vitiligo survived for up to 7 years and 5 months: a case report

1.1. Background: Malignant melanoma is a highly malignant tu mor caused by abnormal proliferation of melanoma cells in the skin and mucous membranes, with a poor prognosis after metasta sis. Skin melanocytes are gradually destroyed in vitiligo patients. There is a certain correlation between these two diseases: In these two conditions, cytotoxic T lymphocytes that target autoantigens shared by normal melanocytes and melanoma cells have been found. Spontaneous melanoma-associated vitiligo was relatively rare before melanoma was diagnosed, and its pathogenesis and prognosis were rarely studied.
