Hypertrophic osteoarthropathy and intrathoracic Hodgkin disease of childhood

Digital clubbing occurring in intrathoracic Hodgkin lymphoma: A case report

RATIONALE

Digital clubbing is rarely associated with lymphoma. This study reports a case of intrathoracic Hodgkin lymphoma with digital clubbing and reviews the current literature regarding the clinical characteristics of this condition.

PATIENT CONCERN

A 21-year-old woman presented with a 3-month history of cough and 1 month of fever, with apparent digital clubbing. A computed tomography (CT) scan of the lungs revealed a large pulmonary mass.

DIAGNOSIS

A CT-guided transthoracic needle biopsy was conducted. Pathology determined a diagnosis of Hodgkin lymphoma.

INTERVENTIONS

The patient underwent 6 courses of chemotherapy and intensification, followed by autografting.

OUTCOMES

The patient recovered and a complete hematological remission was obtained. The patient is alive with no evidence of disease 60 months after diagnosis, with the digital clubbing of the fingers and toes completely resolved.

CONCLUSION

Patients with digital clubbing and intrathoracic lesions need to be examined carefully to determine tumor malignancy.

Nail abnormalities associated with systemic pathologies

Nail abnormalities can arise in conjunction with or as a result of systematic pathologies. These pathologies include single-organ diseases, multisystemic diseases, and drug-induced insults. Clinical signs associated with these conditions include dyschromias, vascular alterations, periungual tissue changes, textural dystrophies, contour alterations, and growth-rate alterations. The associated systemic pathologies may affect any part of the nail apparatus, including the nail matrix, the nail plate, the nail bed, the underlying vasculature, and the periungual tissues. The anatomical location and extent of damage determine the clinically manifested anomaly.

Nail disorders as signs of pediatric systemic disease

Herein, we describe some of the more common changes in the nail unit that can be seen in systemic diseases in children. Changes that can be seen are not limited to those discussed in the following pages. The presence of changes on multiple nails is suggestive of a systemic cause in an ill child. However, multiple nails can also be affected in primary inflammatory disorders and infections of the nail unit. When evaluating a pediatric patient with a nail disorder, it is important to perform a complete physical examination of the skin and oral mucosa, as other clues to the diagnosis of the nail problem may be found. A comprehensive family history is also important to uncover possible syndromic associations with nail disease or diseases that can manifest with nail changes.

Periostitis and hypertrophic pulmonary osteoarthropathy: report of 2 cases and review of the literature

OBJECTIVES

To demonstrate the clinical spectrum of hypertrophic osteoarthropathy (HOA).

METHODS

We report 2 cases of HOA and performed a computer-assisted search of Medline/PubMed for the medical literature from 1960 to June 2008 using the keywords HOA, periostitis, and clubbing. These were also combined with the text words cancer, rheumatic disease, etiology, pathogenesis, hypothesis, transplant, and treatment. Only the English language literature, with pertinent information, was included.

RESULTS

Our 2 cases include 1 HOA case with clubbing, in a patient with a right to left shunt from cryptogenic cirrhosis and interstitial lung disease, and 1 HOA case without apparent clubbing, in a patient with chronic lung transplant rejection secondary to tobacco smoking and related emphysema. Review of the literature has shown that HOA is associated with a wide variety of disorders, approximately 80% are found with primary or metastatic pulmonary malignancies. Various rheumatic diseases, such as systemic vasculitis, can also be associated with HOA. With respect to the pathogenesis, vascular endothelial growth factor, platelet-derived growth factor, and platelets may play crucial roles. Therapeutically, bisphosphonates, such as pamidronade or octreotide, may be tried to relieve symptoms in refractory cases.

CONCLUSIONS

HOA, especially periostitis without clubbing, may go unrecognized. Involvement of vascular endothelial growth factor, platelet-derived growth factor, and platelets in the pathogenesis of HOA has been postulated and supported by recent data. HOA may present as a partial syndrome without clubbing and about 20% of cases have HOA without detectable malignancy. One of our cases represents the first report of the association of HOA with lung transplantation.

Childhood intrathoracic Hodgkin lymphoma with hypertrophic pulmonary osteoarthropathy: a case report and review of the literature

Hypertrophic osteoarthropathy (HOA) is characterized by clubbing, periosteal new bone formation and polyarthritis. The pathogenesis of clubbing involves an increased expression of platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) from the digitally lodged platelet clumps, which bypass the pulmonary capillary network as a result of various systemic disorders. Intrathoracic neoplasms are rare causes of HOA in children. We report here a 14-year-old boy with digital clubbing, who eventually received the diagnosis of intrathoracic Hodgkin lymphoma (HL) and HOA. Eight cases previously reported with these two diagnoses are reviewed to emphasize the prognostic significance of HOA in childhood HL.

CONCLUSION

Given the pathogenesis of clubbing and the prognostic significance of HOA, intrathoracic disease should be considered when HOA is detected in a child with a known or suspected malignant disease, and the occurrence of HOA during follow-up should alert the physicians for possible recurrence of the neoplastic disease or intrathoracic involvement.

Hypertrophic osteoarthropathy and intrathoracic Hodgkin's disease in children

BACKGROUND

Hypertrophic osteoarthropathy (HOA) is a syndrome characterized by clubbing of the fingers and toes, periosteal new bone formation of the long bones and polyarthritis.

CASE REPORT

In this report, two children with intrathoracic Hodgkin's disease and HOA are presented.

CONCLUSIONS

Intrathoracic neoplasms are one of the major causes of HOA in adults; however HOA is rarely associated with intrathoracic malignancies in children. HOA associated with intrathoracic Hodgkin's disease is even more rare, but should be kept in mind.

Clubbing: an update on diagnosis, differential diagnosis, pathophysiology, and clinical relevance

Finger clubbing can be a striking physical finding. At other times, the presence of clubbing is difficult to establish by subjective examination alone and the profile angle or distal phalangeal to interphalangeal depth ratio are needed to confirm the finding. Most microscopic and imaging studies of clubbed fingers reveal hypervascularization of the distal digits. Recent research shows that when platelet precursors fail to become fragmented into platelets within the pulmonary circulation, they are easily trapped in the peripheral vasculature, releasing platelet-derived growth factor and vascular endothelial growth factor, promoters of vascularity and, ultimately, clubbing. Clinically, clubbing is associated with a number of neoplastic, pulmonary, cardiac, gastrointestinal, infectious, endocrine, psychiatric, and multisystem diseases. In narrowing the differential diagnosis, we recommend a detailed history and physical examination accompanied by focused laboratory and imaging studies. An algorithm for the evaluation of newly diagnosed clubbing is suggested.

Multiple cavitating pulmonary nodules and clubbing in a 12-year-old girl

We report on a 12-year-old girl with a prolonged history of cough and hemoptysis on three occasions. X-ray and computed tomography of the chest showed several cavitating lesions and mediastinal lymphadenopathy. Lung biopsy revealed nodular sclerosing Hodgkin's disease. Hodgkin's disease should be considered in the differential diagnosis of cavitating pulmonary lesions.

Sarcoma after radiation therapy: retrospective multiinstitutional study of 80 histologically confirmed cases. Radiation Therapist and Pathologist Groups of the Fédération Nationale des Centres de Lutte Contre le Cancer

PURPOSE

To evaluate the best strategy for treatment of sarcoma that occurs after radiation therapy.

MATERIALS AND METHODS

Records were retrospectively reviewed for 80 patients with a confirmed histologic diagnosis of sarcoma that occurred after radiation therapy performed during 1975-1995. The patients were treated for breast cancer (n = 33, 42%), non-Hodgkin lymphoma (n = 9, 11%), cervical cancer (n = 9, 11%), benign lesions (n = 4, 5%), or other tumors (n = 25, 31%). Sarcoma occurred after a mean latency of 12 years (range, 3-64 years), with most (70%) developing in the soft tissue. Treatment included surgery (28 patients), surgery and chemotherapy (18 patients), chemotherapy only (15 patients), and radiation therapy (14 patients).

RESULTS

By the end of the study, 51 patients were dead, including 46 due to sarcoma. Median survival was 23 months. Overall survival rates at 2 and 5 years, respectively, were 69% and 39% for patients treated with surgery, 10% and 0% for those treated with chemotherapy, and 52% and 35% for those treated with surgery and chemotherapy (P =.001). The 2- and 5-year rates for survival without recurrence were 54% and 32%, respectively.

CONCLUSION

The results confirm the beneficial effect of surgery. Further study is needed to explore the roles of combined treatments.
