ABSTRACT Myopericytomas are perivascular myoid neoplasms that rarely exhibit malignant characteristics. They usually arise in the dermis or subcutaneous tissue and exceptionally involve deep soft tissues, with spinal localization being rare. We report the case of a previously healthy 32-year-old pregnant woman who presented with pain in the interscapular region and progressive loss of lower limb strength. Magnetic resonance imaging revealed a solid neoplastic mass at the T3 level, with spinal canal invasion and spinal cord signal abnormalities. The pregnancy […]

ABSTRACT Hypothyroidism is most frequently caused by Hashimoto’s thyroiditis. While thyrotropin receptor antibodies are well-known in Graves’ disease-induced hyperthyroidism, their role in hypothyroidism is emerging. We report the case of a 37-year-old woman with facial and periorbital edema, weight gain, and hoarseness suggestive of hypothyroidism. Elevated thyroid stimulating hormone (TSH; 131mIU/L) and decreased free thyroxine (0.2ng/dL, 2.6pmol/L) levels confirmed this diagnosis. Laboratory findings showed dyslipidemia, impaired renal function, elevated creatine phosphokinase levels, and anemia. Despite negative results for thyroid peroxidase […]

ABSTRACT This article describes the occurrence of cardiac tamponade in a premature newborn after the use of a peripherally inserted central catheter at a university hospital in Brazil. Pericardiocentesis was performed, the catheter was repositioned using radiography, and minimal residual pericardial effusion was confirmed using echocardiography. The patient showed good progress and was discharged from the hospital on day 47 of life without any complications related to the event. Therefore, although adverse events may occur following the insertion of peripherally […]

ABSTRACT The increasing use of videolaparoscopy for the complete excision of endometriotic lesions and restoration of pelvic anatomy has helped improve long-term outcomes. However, risks remain, including rare but significant complications such as salpingoureteral fistulas. Early diagnosis using imaging methods enables adequate treatment and reduces the risk of new complications. In this report, we present a case of uretero-fallopian fistula following gynecological surgery for the resection of endometriotic lesions, with intraoperative inadvertent ureteral injury. This case report aimed to highlight […]

ABSTRACT Polymethylmethacrylate is a microsphere-based plastic used in aesthetic procedures. However, it can cause granuloma formation and severe hypercalcemia, often accompanied by renal impairment, which is a significant concern. Despite increasing reports, there is no standardized treatment approach for polymethylmethacrylate-induced hypercalcemia, and its incidence remains underreported. In this study, we present three cases of polymethylmethacrylate users who developed severe hypercalcemia that was resistant to conventional treatments, resulting in deteriorating renal function. These patients achieved symptom control with cinacalcet, a medication […]

ABSTRACT Mycoplasma-induced rash and mucositis is a distinctive subset of reactive infectious mucocutaneous eruption identified in 2015 to differentiate it from other mucocutaneous disorders such as Stevens-Johnson syndrome, erythema multiforme major, and toxic epidermal necrolysis. Although its pathophysiology is not completely understood, Mycoplasma-induced rash and mucositis is characterized by polyclonal B cell proliferation, production of antibodies against Mycoplasma pneumoniae, subsequent immune complex deposition, and keratinocyte apoptosis. Clinical manifestations include scattered cutaneous lesions and severe mucositis, which predominantly affect children and […]

ABSTRACT Moebius Syndrome is a genetic condition that results in inability for facial mimicry due to palsy of cranial nerves VI and VII. Syringomyelia is characterized by a dilation of the central canal in the spinal cord, and is generally asymptomatic. Both disorders are diagnosed using imaging tests. A newborn with no facial movements upon physical examination was admitted to the delivery room of our hospital. A specialist confirmed the condition to be Moebius Syndrome. Further investigation using magnetic resonance […]

ABSTRACT Fungal infections have become a public health problem owingdute to their progressive increase in recent decades and high morbidity rates. Fungal bone and joint infections result from direct inoculation, contiguous infection spread, or hematogenous seeding of organisms. Trichosporon spp. are yeast-like basidiomycetes, with Trichosporon asahii being the most common pathogenic species. This article describes a rare case of tenosynovitis caused by Trichosporon asahii in an immunocompetent patient. Treatment with voriconazole resulted in an excellent clinical response.

ABSTRACT Chryseobacterium indologenes is a Gram-negative aerobic bacillus commonly found in nosocomial environments, particularly in patients with prolonged hospital stays or those requiring long-term invasive devices. It primarily affects elderly and immunocompromised individuals. This microorganism is associated with multidrug resistance, which is a crucial factor in treatment decisions. Here, we report a case of C. indologenes infection in an infant following the ingestion of milk formula diluted with untreated water.

ABSTRACT The etiologies of vulvar nodules range from infectious to neoplastic. Owing to the wide spectrum of vulvar diseases, clinical differentiation of the lesions is crucial for adequate diagnosis and management. A 46-year-old patient presented with a nodular lesion in the vulvar region that had been growing slowly for 10 years. Gynecological examination revealed the presence of a solid nodular lesion measuring approximately 3 cm in the middle third of the right labia majora without phlogistic signs or secretion discharge.
