Bilateral Parsonage-Turner syndrome after COVID-19 vaccination. A case report and review of the literature / Kétoldali Parsonage-Turner-szindróma COVID-19-vakcinációt követoen. Esetismertetés és az irodalom áttekintése

Parsonage---Turner syndrome (PTS; neuralgic amyotrophy) is a generally unilateral neuritis with sudden onset, severe shoulder or upper arm pain. Although the intense pain is usually self-limiting, two-thirds of patients experience pro-gressive motor weakness, narrowed range of motion, reflex changes, dysesthesias and chronic neuropathic pain in the shoulder girdle musculature and proximal upper limb muscles. The aetiology is unclear, in addition to some idiopath-ic cases the most common triggers of PTS are surgery, trauma, infection or vaccination. It is reported after SARS-CoV-2 infection, and unilateral PTS has been described in some cases following different types of COVID-19 vaccines. We are currently presenting the case of a middle-aged woman who developed partial neuralgic amyotrophy on the right shoulder one month after receiving the second dose of the BNT162b2 COVID-19 mRNA vaccine (Pfizer-BioNTech), and seven months later the symptoms appeared in the contralateral upper limb. The diagnosis of PTS was also confirmed by magnetic resonance and electrodiagnostic examination. The PTS is not an uncommon condi-tion, but in the absence of knowledge it is rarely thought of. The purpose of this report is to draw attention to the possibility of PTS in shoulder or upper arm pain following both SARS-CoV-2 infection and COVID-19 vaccination, as early diagnosis and adequate therapy may help to shorten the course of the disease.

[Tomato peel: rare cause of biliary tract obstruction]. / Paradicsomhéj: az epeúti elzáródás ritka oka.

Foreign bodies in the biliary tree are rare causes of obstructive jaundice. Food bezoars are infrequent as well. They can cause biliary obstruction after biliary tract interventions, or in the presence of biliary-bowel fistula or duodenum diverticulum. Food bezoars usually pass the gastrointestinal tract without any symptoms, but they can cause abdominal pain and obstructive jaundice in the case of biliary tract obstruction. Endoscopic retrograde cholangio-pancreatography has the major role in the diagnosis and the treatment of the disease. Authors summarize the medical history of a 91-year-old female patient, who developed vomiting and right subcostal pain due to the presence of tomato peel within the ductus choledochus.

Gastrointestinal stromal tumor presenting as a hormonally inactive adrenal mass.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Rarely, tumors with the same histological and immunohistochemical features arise in organs having no connection to the tubular gastrointestinal tract designated as extra-gastrointestinal stromal tumors (EGISTs). In this article, we report the first case of an EGIST presenting as a hormonally inactive adrenal mass. A 68-year-old woman with a 3-month history of right abdominal pain was clinically diagnosed as having a hormonally inactive right adrenal tumor sizing 15 cm in diameter. This mass and the tightly fixed right adrenal gland were resected en bloc.Histologically, the tumor was composed primarily of monomorphic spindle cells. Mitotic figure was 2­3 per 50 high power fields. Immunohistochemical analysis revealed strong positivity for CD117 (c-KIT) and smooth muscle actin (a-SMA), but negativity for beta-catenin, CD34, pan-keratin,S-100, desmin, and H-caldesmon. Genetic analysis showed no mutations in KIT gene exons 9, 11, 13, and 17,and in exon 18 of the platelet-derived growth factor-2 receptor gene (PDGFR). The patient proved to be tumor-free at the 18-month follow-up. This case under study demonstrates that EGIST should be included in the differential diagnosis of hormonally inactive adrenal tumors.CD117 (c-KIT) immunohistochemistry should be applied in the pathological workup of soft tissue adrenal tumors.This case is an additional example suggesting that the prognosis of even a very large EGIST is not definitely grave.
