ABSTRACT
Takayasu arteritis, also known as "pulseless disease" usually affects major vessels like aorta and its branches, pulmonary arteries, and renal arteries. Hypertension is the common presentation. Chronic kidney disease involvement is less common. Only a few chronic kidney disease cases are reported so far in Takayasu arteritis. We discuss a case of a young female who presented with accelerated hypertension with chronic kidney disease with preserved peripheral pulses. The diagnosis was confirmed by Computed tomography aortic angiogram, which showed diffuse circumferential thickening, multifocal ectasia, and aneurysmal dilatation with few saccular outpouchings of the aortic arch, descending thoracic and abdominal aorta (Type V). The patient was treated with steroids, antihypertensives, antiplatelet, and hemodialysis.

Carcinoma of the breast with apocrine differentiation also known as apocrine adenocarcinomas is special histological subtypes comprising approximately 1% of breast cancers. They are estrogen receptor/progesterone receptor-negative and androgen receptor-positive tumors having more than 90% population of tumor cells with apocrine morphology. We present a 49-year-old woman with a breast lump in the right upper outer quadrant clinically and radiologically diagnosed as malignancy and histologically proven as apocrine adenocarcinoma of the breast owing to the morphology comprising tumor cells having abundant granular cytoplasm, central to the eccentric nucleus and prominent nucleoli. On immunohistochemistry, it was a triple-negative tumor with AR positivity. As apocrine adenocarcinoma of the breast has an uncertain prognosis, variable HER2/neu overexpression, debatable responses to neoadjuvant therapy, and probable response to androgen therapy, the onus of diagnosing and reporting these tumors accurately lies with the pathologist. Moreover, as the presentation of these tumors is similar to invasive breast carcinoma, no special type but with potentially different and useful theranostic markers, an emphasis on specifying this histological subtype is becoming increasingly essential.

Direct carotid-cavernous fistula (CCF) refers to direct communication between the cavernous portion of the internal carotid artery (ICA) and the cavernous sinus due to rent in the ICA, most commonly secondary to trauma. These are generally high-flow fistula and rarely resolve spontaneously. We report a case of a young male who developed features of direct CCF after trauma, was denied any treatment for 4 years, and then presented with spontaneous thrombosis of the fistula and a residual large pseudoaneurysm of the cavernous segment of the right ICA, which was subsequently managed with parent vessel occlusion.
