Abstract
INTRODUCTION: Acquired haemophilia-A, although uncommon in elderly patients, poses significant clinical challenges, especially when associated with profound musculoskeletal complications. The potential mimicry of hematomas as tumors further complicates the diagnostic process. CASE PRESENTATION: An 85-year-old male, with a remote history of hypertension, benign prostatic hyperplasia, and right inguinal hernia, presented with acute pain in the left lower limb, functional limitation, and deep hematomas in the ileopsoas and axillary region. Initial suspicions of a sarcomatous lesion in the ileopsoas, based on radiological findings, were refuted following histopathological examinations, which confirmed the presence of necrotic hemorrhagic tissue. The patient underwent a one-month physical therapy regimen, targeting lower extremity muscles, especially around the hip joint. CLINICAL DISCUSSION: The severity of the presentation and the involvement of vital muscles like the ileopsoas and quadriceps underscored the importance of comprehensive rehabilitation. Consistent therapeutic interventions, targeting muscle strength and joint function, demonstrated marked improvement as evidenced by the HJHS, HAL, and FISH scores. The multidisciplinary approach, entailing hematological, rehabilitative, and supportive measures, was paramount in ensuring holistic patient recovery. CONCLUSIONS: Acquired haemophilia-A in the elderly necessitates an integrative care approach, encompassing accurate diagnosis and tailored therapeutic interventions. This case emphasizes the transformative potential of dedicated physiotherapy in managing the musculoskeletal implications of this bleeding disorder, underscoring the value of early intervention and comprehensive care.
