Interesting Adult Granulomatous Cases (Pearls, "Pitt"-falls and Illustrative cases)

Conclusions

• The case of the 61-year-old male patient was diagnosed with multiple adult-onset xanthogranuloma non-Langerhans cell histiocytosis and associated follicular mucinosis.
• The diagnosis indicated a need for smoking cessation to mitigate lung involvement in Langerhans cell histiocytosis.
• Treatment for chronic myelogenous leukemia included various chemotherapeutic agents, which resulted in adverse reactions and loss to follow-up.
• The second case presented a 27-year-old female diagnosed with multicentric reticulohistiocytosis, which affected her during pregnancy and was managed successfully with systemic steroids.
• Pregnancy may exacerbate multicentric reticulohistiocytosis, resulting in an increased risk for complications such as pre-eclampsia.
• The third case involved a 65-year-old female with a rash leading to the diagnosis of reactive granulomatous dermatitis, suggestive of an autoimmune condition that manifested after the dermatitis appeared.
• Follow-up is crucial as patients with reactive granulomatous dermatitis can develop associated systemic diseases, highlighting the importance of continued monitoring.
