ABSTRACT

BACKGROUND: Cytomegalovirus (CMV) pulmonary involvement is rarely associated with IRIS; therefore, limited information is available. CASE PRESENTATION: Here, we describe the case of a 43-year-old HIV-infected male who developed an unusual case of IRIS after cytomegalovirus (CMV) pneumonia. Clinically there was a progressive and paradoxical worsening of respiratory distress, despite being treated for CMV after initiation with antiretroviral therapy. Chest X-ray revealed disseminated infiltrates in both lungs; chest CT-scan showed generalized lung involvement and mediastinal adenopathy. Pulmonary biopsy confirmed CMV pneumonia with the observation of typical viral inclusions on pneumocytes. CONCLUSIONS: CMV pneumonia can be associated with the development of IRIS requiring treatment with immunosuppressant's and immunomodulatory drugs.

ABSTRACT

Gorham-Stout disease (GSD) is a rare condition of osteolysis with excessive lymphangiogenesis within bone tissue. The etiology of this condition remains unknown but seems to affect mainly children and young adults of both genders all over the world. Unfortunately, there is no standardized method for diagnosis; however, histopathology remains as the gold standard. This condition is often misdiagnosed due to its varying clinical presentations from case-to-case. Here, we report the case of an 8-year-old girl who presented with chronic mandibular pain during mastication and received multiple antibiotic treatment due to infectious origin suspicion. After integrating information from clinical manifestations, radiographic, laboratory, and histopathology information, she was diagnosed with GSD. Additionally, due to the lack of literature with respect to insights into biological mechanisms and standardized treatment for this condition, we underwent a literature revision to provide information related to activation of cells from the immune system, such as macrophages, T-cells, and dendritic cells, and their contribution to the lymphangiogenesis, angiogenesis, and osteoclastogenic process in GSD. It is important to consider these mechanisms in patients with GSD, especially since new studies performed in earlier stages are required to confirm their use as novel diagnostic tools and find new possibilities for treatment.
