Case report: Dramatic response to pralsetinib in an elderly patient with advanced RET-fusion positive papillary thyroid carcinoma.

We are recently faced with a progressive evolution of the therapeutic paradigm for radioiodine refractory differentiated thyroid cancer (RAI-R DTC), since the advent of tissue agnostic inhibitors. Thus, tumor genotype assessment is always more relevant and is playing a crucial role into clinical practice. We report the case of an elderly patient with advanced papillary thyroid carcinoma (PTC) harboring fusion with four co-occurring mutations involving , , and mutations, treated with pralsetinib under a compassionate use program.

(68)Ga-DOTANOC PET/CT detection of multiple extracranial localizations in a patient with anaplastic meningioma.

We report herein a case of a 65-year-old male with intracranial recurrence of atypical meningioma initially treated with a combination of surgical resection and gamma knife radiotherapy. Afterwards, he underwent a (68)Ga-DOTANOC PET/CT scan in order to evaluate the feasibility of peptide receptor radionuclide therapy (PRRT). The scan identified multiple pulmonary, pleural and lymph node localizations.

Imported visceral leishmaniasis - unexpected bone marrow diagnosis in a patient with fever, pancytopenia, and splenomegaly.

Leishmaniasis is spreading from mediterranean countries to the north of Europe. The Alps are not an endemic region and there are only few reports of sporadic cases. We report the case of a 72 year old male who presented after a syncope with fever, cough and a sacral skin rash.

FDG PET/CT in malignant eccrine porocarcinoma arising in a pre-existing poroma.

In a 61-year-old man with known poroma of right lower abdomen, malignant transformation to porocarcinoma was suspected and confirmed by biopsy. PET/CT was requested for tumor staging, which revealed high FDG uptake in the known skin nodules located in the right side of abdominal and chest wall and identified further some adenopathy in the right axillary. All nodules and axillary lymph nodes were removed, and diagnosis of eccrine porocarcinoma was confirmed.

Clinical significance of axillary findings in patients with lymphoma during follow-up with 18F-fluorodeoxyglucose-PET.

Purpose: The aim of this study was to evaluate the clinical significance of positive axillary findings in patients with Hodgkin's disease and non-Hodgkin's lymphoma during follow-up with 18F-fluorodeoxyglucose-PET.

Materials And Methods: We retrospectively reviewed PET scans carried out in 543 patients during follow-up. Patients with reports describing any increased fluorodeoxyglucose uptake at the axillary level were selected (106 cases) and final assessment of the findings was available in 78 patients (17 Hodgkin's disease, 51 non-Hodgkin's lymphoma).
