Hodgkin's disease and ataxia telangiectasia with pulmonary cavities

PEDIATRIC PULMONOLOGY, Issue 5 2002
Bilgehan Yalçin MD
Abstract Ataxia telangiectasia (AT) homozygotes have an increased risk for development of Hodgkin's disease (HD). Parenchymal lung involvement is not uncommon in HD; however, cavitary pulmonary lesions are quite unusual. We report on 3 cases of AT with HD who had mediastinal disease and parenchymal pulmonary involvement with cavitation. Of 6 AT patients in our HD series, 3 developed pulmonary cavities. The patients displayed pulmonary infiltration, cavitation in the lung parenchyma, and mediastinal enlarged lymph nodes on both plain chest X-rays and thoracic computed tomographies. No infectious etiologies were established for the pulmonary findings. Histopathological examination of open lung and mediastinal biopsies revealed HD, and all patients received multiagent chemotherapies. The outcome was fatal in all 3 patients. Respiratory infections are the principle cause for morbidity and mortality in AT patients. Reports on cavitating pulmonary lesions in HD are quite rare. Furthermore, data regarding the patterns of pulmonary involvement in AT patients with or without HD are lacking. The increased incidence of malignancies in AT patients may relate to immunodeficiency and to the chromosomal alterations identified. Pediatr Pulmonol. 2002; 33:399,403. © 2002 Wiley-Liss, Inc.

Abstract: Two cases of a rare and uncommonly described form of Aspergillus lung disease were diagnosed from incidental CXR abnormalities. This strange presentation has been described in the literature as ,tumour-like blocked pulmonary cavities with liquid content infected by aspergilli'. The details of these two cases are reported together with a discussion of the diagnostic features of the disease and its position in the spectrum of pulmonary diseases caused by Aspergillus.

Cutaneous sarcoid-like granulomas with alveolar hemorrhage and c-ANCA PR-3

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 9 2004
Natividade Rocha MD
A 28-year-old woman, employed as a leather factory worker, noted asymptomatic, well-delimited plaques on both knees, 6 years ago. The plaques were violaceous with a smooth surface. One appeared over a post-traumatic scar from childhood (Fig. 1). Two years later, she began to complain of symptoms suggestive of polyarthritis, first of the small joints of the hands (proximal interphalanges) and then of the larger joints (wrists, elbows, and knees). She was diagnosed with rheumatoid arthritis and began treatment with nonsteroidal anti-inflammatory drugs for 1 month without any change. Deflazacort, 12 mg/day, and hydroxychloroquine, 400 mg/day, were administered for 3 months, with improvement of her articular complaints, but not her skin lesions. Figure 1. Well-delimited, violaceous plaques with a smooth surface on the knees, one over an old post-traumatic scar One year later, she complained of dysphonia, which remitted spontaneously after some weeks. After one additional year, she noted papules, with similar characteristics to the plaques, on the elbows, and two well-delimited orange-to-brown plaques on the forehead (Fig. 2). Figure 2. Orange,brown plaques symmetrically placed on the forehead During the fifth year of the disease, she was referred for the first time to a dermatologist, who biopsied one of the knee lesions. The histologic result was compatible with "sarcoid granuloma." At that time, she presented with skin lesions as her only complaint. Sarcoidosis was suspected based on a chest X-ray, which revealed hilar lymphadenopathy and diffuse accentuation of the interstitium. In November 2000, she suddenly developed fever (40 °C), cough with hemoptysis, dysphonia, and subcutaneous nodules on the palmar surface of the fingers of both hands that were painless, well-delimited, 5 mm in diameter, and firm (Fig. 3). She reported a weight loss of 12 kg in the previous 3 months. Pulmonary condensation was found on auscultation, and she had palpable hepatomegaly. Peripheral lymphadenopathy was not present. Figure 3. Painless, well-delimited, firm subcutaneous nodules on the palmar surface of the fingers Laboratory investigations revealed normochromic, normocytic anemia (hemoglobin, 7.7 g/dL), iron deficit, a white blood cell count of 16,000/µL with neutrophilia, an erythrocyte sedimentation rate of 130 mm/h, elevation of liver enzymes, a slight increase in angiotensin-converting enzyme (ACE) level (72 U/L), hypergammaglobulinemia (IgG, 3350 mg/dL), antinuclear antibody (ANA) of 1 : 320, and a slight increase in CD4 and decrease in CD8 lymphocytes with normal cellular morphology in blood. Renal function, urine sediment, urine and serum calcium, complement (C4), dsDNA, antimitochondrial antibody, direct and indirect Coombs test, antineutrophil cytoplasmic antibody (ANCA), tuberculin skin tests, viral markers of hepatitis B, C, and human immunodeficiency virus (HIV), electrocardiogram (ECG), ophthalmic examinations, and culture for infectious agents in blood and sputum were all normal or negative. Computed tomography (CT) scan showed an infiltrate in the upper right pulmonary lobule with a central cavity and bilateral hilar lymphadenopathy (Fig. 4). Homogeneous hepatosplenomegaly was present. The bronchoalveolar lavage (BAL) showed a slight lymphocytic increase predominantly of CD8 cells and hemosiderosis. Stains for infectious agents, including acid-fast bacillus, fungi, Mycoplasma, and Legionella, were negative. Three biopsies from the forehead, elbows, and knees showed well-formed noncaseating epithelioid cell granulomas with giant cells of the Langhans type in the dermis, suggestive of sarcoidosis (Figs 5 and 6). A fourth biopsy from a finger nodule demonstrated inflammatory infiltration of the dermis and necrosis with cellular debris. Vasculitis was not seen (Fig. 7). Figure 4. Computed tomography scan showing an infiltrate in the upper right pulmonary lobule with a central cavity Figure 5. Beneath a flattened epidermis, several sarcoid granulomas composed of epithelioid histiocytes and several multinucleated giant cells of Langhans type can be seen (hematoxylin and eosin, ×10) Figure 6.

Foci of necrosis and fibrinoid degeneration with some neutrophil infiltration and nuclear dusting (hematoxylin and eosin, ×40) The patient was treated with a broad-spectrum empirical antimicrobial (levofloxacin, 500 mg daily intravenously) over 12 days, with prompt improvement in her symptoms and remission of the forehead and finger lesions. Nevertheless, on the first evaluation after hospitalization, the CT scan showed persistence of the pulmonary cavity (Fig. 8). A repeat ANCA determination was positive (cytoplasmic pattern, c-ANCA) at 1 : 640 by indirect immunofluorescence (IIF). Antiproteinase-3 antibody was demonstrated at 78 by enzyme-linked immunosorbent assay (ELISA). Figure 8. Computed tomography scan showing persistence of the pulmonary cavity She underwent an open lung biopsy which revealed intra-alveolar hemorrhage and scanty noncaseating epithelioid cell granulomas of the sarcoidosis type in the peripheral blood vessels without vasculitis. A diagnosis of Wegener's granulomatosis was made and she began prednisolone (1 mg/kg/day) and oral cyclophosphamide (2 mg/kg/day). One year later, she is asymptomatic, the skin lesions have completely remitted, c-ANCA is negative, and the CT scan shows partial regression of the pulmonary cavity. [source]

Zygomycosis , a case report and overview of the disease in India

MYCOSES, Issue 4 2007
Amit Diwakar
Summary A case of zygomycosis caused by Rhizopus oryzae in a diabetic patient previously misdiagnosed as invasive pulmonary aspergillosis and an overview of the disease in India are presented. The case was diagnosed by direct microscopy, histopathologic examination and culture. Following surgical resection of pulmonary cavity under cover of amphotericin B administration, the patient recovered completely. Of 461 cases reported to-date, approximately 70% had been diagnosed at the Postgraduate Institute of Medical Education and Research, Chandigarh, in north India. This may be attributed to better awareness, expertise and infrastructural facilities for mycological diagnosis than to any particular regional preponderance of the disease. Rhino-orbito-cerebral manifestations were the most common feature of zygomycosis (269 cases), followed by cutaneous disease (66 cases), which is in conformity with the pattern prevalent worldwide. The etiologic agents encountered were Rhizopus oryzae, Apophysomyces elegans, Saksenaea vasiformis, Cunninghamella bertholletiae, Absidia corymbifera, Basidiobolus ranarum and Conidiobolus coronatus. In contrast to cases from the developed world where transplant recipients and patients with haematological malignancies seem to be most vulnerable to zygomycosis, the most common risk factor in India was uncontrolled diabetes mellitus. Amphotericin B was the mainstay of various treatment modalities employed. The relevance of a strong clinical suspicion and early diagnosis of zygomycosis for favourable prognosis can hardly be over-emphasised. [source]
