The authors report a 4-year-old male with Hodgkin's disease with atypical clinical presentation, laboratory data and imaging studies as well as an increased radiosensitivity. These were the first symptoms which raised the suspicion of ataxia-telangiectasia. The lymphoma presented as a solid tumor mass in the right upper posterior mediastinum without peripheral lymphadenopathy. The alpha-fetoprotein was significantly increased and the diagnosis of a germ-cell tumor or neuroblastoma was suspected. After partial resection of the tumor the histology indicated Hodgkin's disease-mixed cellularity. The boy received chemotherapy according to DAL HD-95 protocol without any unusual toxicity. Low-dose radiation therapy of the upper and middle mediastinum was followed by early radiation-induced esophagitis and appearance of a large pericardial effusion one year later. Ataxia and bulbar and skin telangiectasias at the radiation site appeared in the next years. He suffered recurrent pulmonary infections and succumbed to severe pneumonia with respiratory failure and pulmonary hypertension five years after the diagnosis of malignant lymphoma without evidence of recurrence of Hodgkin's disease.
Case ReportThe child was a 4-year-old male of Roma origin, born after second normal pregnancy without family history of immune deficiency. He had a past history of cerebral palsy, diagnosed at the age of 20 months because of a delay in motor and intellectual development. His present complaints were productive cough and fever for one month. After admission to the regional hospital physical and Xray signs of right pulmonary infiltrate were found, and he received antibiotic treatment with Clindamycin, Amikacin, Imipenem, and Cefepime without any improvement. He was referred for further diagnostic evaluation to the Department of Pediatrics, Medical University-Plovdiv. Physical examination on admission showed mask-like, sad, and relaxed face with progeroid features, growth retardation, reduced subcutaneous fat, generalized muscle hypotonia and atrophy, bronchial breathing in the right parascapular region, tracheal stridor, and enlarged liver 3 cm below the costal margin and lack of peripheral lymphadenopathy. Mental retardation was mild (IQ: 60%) with predominantly affected expressive speech and fine motor skills. Computer tomography (CT) scan showed tumor mass in the right upper posterior mediastinum (Figure 1). It deviated the trachea and was well demarked from the pulmonary parenchyma. No destruction of the adjacent bones was evident.Laboratory data showed leukocytosis, thrombocytosis; elevated erythrocyte sedimentation rate, serum fibrinogen and C-reactive protein 221 mg/L. The diagnostic workup for the mediastinal tumor revealed significant increase of alpha-fetoprotein (AFP) 238.98 ng/mL (reference range 0-5 ng/mL), moderate elevation of vanylmandelic acid 80.9 µmol/l, anergic tuberculin test, and negative blood and sputum cultures and serology for ecchinococcus.Germ-cell tumor or neuroblastoma was suspected and the boy was referred to ...
