Technetium pyrophosphate myocardial uptake and peripheral neuropathy in a rare variant of familial transthyretin (TTR) amyloidosis (Ser23Asn): a case report and literature review

Juvenile xanthogranuloma (JXG) is a member of the non-Langerhans cell group of proliferative disorders of mononuclear phagocytes. JXG is a benign tumour of histiocytic cells. Classic JXG is divided into 2 main clinical subtypes: dome-shaped papules (<0.5 cm) and single/multiple nodules (<2.0 cm). A rare variant is referred to as giant; this term encompasses JXG lesions larger than 2.0 cm. In this article, we report a case of a congenital cutaneous giant JXG. In addition, we reviewed and analyzed all cases (n = 51) of giant JXG reported in the English literature. We propose an algorithm for classifying giant JXG based on the following factors: onset of lesions (congenital and acquired), number of lesions (solitary ± satellites and multiple), morphology of cutaneous/mucosal lesions (plaque, nodular, ulcerated-nodular, macular, and other), and extracutaneous manifestations.

Pleomorphic Sarcoma

Pleomorphic sarcoma of the larynx is a rare variant of laryngeal cancer. We present the case of a 59-year-old male patient who has been smoking for 40 years. He presented with signs and symptoms of an obstructive glottic mass. The diagnostic workup pointed to a malignant pathology; the histopathology report confirmed the diagnosis of glottic undifferentiated pleomorphic sarcoma (malignant fibrous histiocytoma).

The article presents a case of preoperative diagnostics of a rare variant purulent-inflammatory kidney disease in children – the kidney carbuncle. The rarity of the pathology and the early child’s age (5 years old) determined complexity of clinical diagnostics and the importance of radiation research methods. The diagnosis was suspected by ultrasound diagnostics and confirmed by CT. The child was operated on (resection of the upper pole of the kidney), and clinical recovery was achieved. The article includes illustrative material and a brief review of the literature on this problem.
