Radiation-induced cutaneous vasculopathy of the breast: a rare case report.

BACKGROUND: Radiation therapy is often indicated as part of the treatment for breast cancer and is therefore used frequently worldwide. Vasculopathy is a general term used to describe any condition that affects blood vessels. We present a case report of a patient who presented with vasculopathy as a rare late side effect of radiation therapy to the breast. CASE PRESENTATION: This 66-year-old woman was initially treated with breast-conserving surgery for early-stage receptor-positive left breast carcinoma. She received postoperative radiation therapy and hormonal treatment with tamoxifen. She developed sudden spontaneous painless ecchymosis spread over the whole irradiated area 1.5 years after finishing her radiation therapy. Tumor relapse was excluded. There was no associated vasculitis. The cause was presumed to be multifactorial. She had a history of smoking and was known to have hyperlipidemia. She had undergone several surgical treatments at the left breast one year after her initial breast-conserving treatment and was taking tamoxifen. Anti-inflammatory medicine and treatments increasing local blood flow were prescribed. The ecchymosis resolved completely within one month. CONCLUSIONS: Vasculopathy can occur as a rare late side effect of radiation therapy. It can be reversible. Prevention begins with carefully treating precipitating factors.

ARMC5-negative primary bilateral macronodular adrenal hyperplasia.

A woman in her 60s with chronic fatigue, depressed mood and proximal muscle weakness was referred to our endocrinology department. Physical examination revealed facial plethora, atrophic skin and ankle oedema. Adjuvant blood and urine analyses indicated endogenous ACTH-independent Cushing syndrome. Abdominal imaging showed bilateral macronodular adrenals, measuring 58.9 × 29.7 mm on the right and 55.6 × 42.6 mm on the left. Primary bilateral macronodular adrenal hyperplasia was confirmed by pathology after bilateral adrenalectomy. Gradual mental and physical recovery was observed in the months following surgery. Genetic sequencing failed to reveal mutations in the ARMC5 gene.Cushing syndrome is a rare entity that should be suspected when typical clinical signs, including skin atrophy with ecchymosis, muscle weakness or coloured stretch marks, are present. Primary bilateral macronodular adrenal hyperplasia is an uncommon cause of endogenous Cushing syndrome. It is a benign condition characterised by adrenal macronodules exceeding 1 cm and hypercorticism.

Ureteral Metastasis: Uncommon Manifestation in Prostate Cancer.

Ureteral metastasis from a primary prostate cancer is a rare event in the initial diagnosis and progression of prostate cancer. We report here the case of a 72- year-old patient who was treated for castration-resistant metastatic prostate cancer involving bone, intra-abdominal lymph nodes, bilateral adrenal glands, and a small distal ureteral lesion with left hydronephrosis considered in remission, with a luteinizing hormone-releasing hormone analog plus abiraterone acetate (AA) and prednisone after initial docetaxel plus prednisone chemotherapy. After an episode of acute left flank pain, the previous left distal intraluminal ureteral mass appeared increased in volume on computed tomographic scan and was compatible with either a metastasis from prostate cancer, transitional cell carcinoma of the ureter, or a collision tumor. After left nephroureterectomy (NU), the mass was confirmed to be of prostatic origin on histopathological examination and the only site of metastatic progression of prostate cancer. Abdominal CT-scan and the operative specimen of the NU showed no direct extension of the abdominal lymph nodes into the ureteral lesion. We speculate that this unique ureteral prostate cancer metastasis was the result of hematogenic spread of prostate cancer, although microscopic spread through the lymphatic system could not be excluded. The transient anti-tumor effect of AA plus prednisone at the level of ureteral metastasis, as far as we are aware of, has never been documented before.

Spontaneous bilateral carotid artery dissection following cervical manipulation.

We report an autopsy case of a bilateral carotid artery dissection, following cervical manipulation by a chiropractor. To establish the etiology of a cervical artery dissection is important in view of possible legal implications and to exclude hereditary disorders, since cervical artery dissection has been linked to several arteriopathies. The underlying arteriopathy in the presented case was an idiopathic cystic medial degeneration. This report emphasizes the role of the pathologist in defining the underlying arteriopathy in carotid artery dissection.
