Primary hypertrophic osteoarthropathy related gastrointestinal complication has distinctive clinical and pathological characteristics: two cases report and review of the literature. Orphanet J Rare Dis 2019; 14:297. [PMID: 31878983 PMCID: PMC6933916 DOI: 10.1186/s13023-019-1264-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Accepted: 11/22/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Primary hypertrophic osteoarthropathy (PHO) is a rare disease related to HPGD and SLCO2A1 gene mutation. Gastrointestinal involvement of PHO is even rarer with unknown pathogenesis. Clinical features of GI complication in PHO mimics other auto-immune based bowel entities, such as inflammatory bowel diseases and cryptogenic multifocal ulcerous stenosing enteritis (CMUSE). We aimed to analyze the clinical, genetic, radiological and pathological features of Chinese patients with PHO and determine the difference between PHO patients presenting with and without GI involvement. METHODS We reported two PHO cases with gastrointestinal involvement and reviewed all the studies of PHO in Chinese population published from January 1, 2000, to April 30, 2018. Clinical and genetic presentations of PHO in Chinese patients were analyzed. We compared the characteristics of those patients with gastrointestinal involvement against those without. RESULTS The two patients were both males with complete-form PHO for more than 10 years. GI related symptoms included diarrhea, chronic gastrointestinal hemorrhage, incomplete intestinal obstruction, anemia, and edema, which were unresponsive to etoricoxib treatment. Radiological examinations revealed segmental intestinal stenosis and thickened intestinal wall. Endoscopic findings included multiple ulcers and mucosal inflammation. Both patients had mutations of SLCO2A1 according to sequence analysis. The surgical pathology revealed chronic inflammation involving the intestinal mucosa and submucosa, similar to histological changes in CMUSE. According to the systemic review of 158 Chinese patients with PHO, 17.2% had gastrointestinal involvement, including peptic ulcer, gastric polyps, hypertrophic gastritis, and segmental intestinal stenosis. Patients with gastrointestinal involvement were more likely to have anemia (40.0% vs. 4.5%, P < 0.001), hypoalbuminemia (16.7% vs. 0.9%, P = 0.003), and myelofibrosis (19.0% vs. 0.9%, P = 0.002) than those without. Most patients with gastrointestinal complication had SLCO2A1 mutation (86.7%, 13 /15). CONCLUSIONS Digestive tract involvement is uncommon in patients with PHO and often presents with anemia, and hypoalbuminemia resulted from intestinal inflammation. The intestinal pathologic characteristics are distinct from Crohn's disease but similar to CMUSE. Mutations in SLCO2A1 might be the pathogenic cause of GI involvement of PHO. NSAIDs may not be effective for PHO patients with gastrointestinal complications.

Abstract
OBJECTIVE To evaluate through differential diagnosis whether hypertrophic osteoarthropathy was present on an adult macaque skeleton. MATERIALS Skeletal remains of a well-preserved adult macaque (Macaca) of unknown species curated by the archaeology department at University College London. METHODS Macroscopic and radiographic evaluation of pathological lesions. RESULTS Widespread bilateral and symmetrical periosteal new bone growth primarily affecting the limbs was observed. CONCLUSION A careful differential diagnosis of the lesions and comparison with previously published cases of hypertrophic osteoarthropathy among humans and non-humans suggests this animal displays a case of Hypertrophic osteoarthropathy. SIGNIFICANCE Only been three reported cases of HOA in non-human primates have been reported, and all were apes. This study serves as the first reported case of HOA among non-hominoid simians, providing a detailed description of the skeletal lesions to aid future with paleopathological analyses. LIMITATIONS Small sample sizes for comparison and lack of context for this specimen limits discussion of the scope of this disease among non-human primates. SUGGESTIONS FOR FURTHER RESEARCH Re-evaluate skeletal collections which have not been subject to recent osteological and pathological analysis.

Abstract
A 4-year-old boy was referred because of pan-digital clubbing and watch-glass nails. Other remarkable findings were: surgical closure of a patent arterial duct, decreased knee-mobility and consanguineous parents. This combination is suggestive for primary hypertrophic osteoarthropathy (PHO; #OMIM 259100). PHO was proven by his homozygous mutation of the 15-hydroxyprostaglandine dehydroxygenase-gene.

Abstract
Pachydermoperiostosis (PDP), or primary hypertrophic osteoarthropathy, is a rare genetic disease affecting both skin and bones. Both autosomal dominant with incomplete penetrance and recessive inheritance of PDP have been previously confirmed. Recently, hydroxyprostaglandin dehydrogenase (HPGD) and solute carrier organic anion transporter family member 2A1 (SLCO2A1) were reported as pathogenic genes responsible for PDP. Both genes are involved in prostaglandin E2 (PGE2) degradation. We aimed to identify responsible genes for PDP and the clinical features in Korean patients with PDP. Six affected individuals and their available healthy family members from three unrelated Korean families with PDP were studied. All of the patients displayed complete phenotypes of PDP with finger clubbing, pachydermia, and periostosis. Mutation analysis revealed a novel heterozygous mutation in the SLCO2A1 gene at nucleotide 302 causing a substitution of the amino acid isoleucine to serine at codon 101 (p.IIe101Ser) in affected individuals. We also identified known SLCO2A1 mutations, one homozygous for c.940+1G>A, and another compound heterozygous for c.940+1G>A and c.1807C>T (p.Arg603*) from two PDP families. Genetic analyses of the PDP patients showed no abnormality in the HPGD gene. Our study further supports the role of mutations in the SLCO2A1 gene in the pathogenesis of PDP and could provide additional clues to the genotype-phenotype relations of PDP.

Abstract
Primary hypertrophic osteoarthropathy is a condition characterized by clubbing, arthropathy and periostosis of long tubular bones. Three variants of primary hypertrophic osteoarthropathy are distinguished: pachydermoperiostosis, which shows as additional symptom pachydermia; cranio-osteoarthropathy, which has a decreased neurocranium ossification as additional feature; and a secondary form. Primary hypertrophic osteoarthropathy is also genetically heterogeneous, with evidence for both autosomal dominant and autosomal recessive inheritance. We describe two sibs with cranio-osteoarthropathy and briefly review previously reported cases. The present cases demonstrate the phenotypic variability of the condition. The consanguinity in the present family and analysis of previously described cases support autosomal recessive inheritance for cranio-osteoarthropathy.

Abstract
Finger clubbing can be a single physical finding. In Touraine-Solente-Gole syndrome, the primary form of hypertrophic osteoarthropathy, it is mostly associated with bone pain, hyperhydrosis, pachydermy and wrinkling of the forehead. In other cases, the presence of clubbing is associated with neoplastic, pulmonary, cardiac or other diseases and is then called Bamberger-Pierre-Marie syndrome, the secondary type of hypertrophic osteoarthropathy. The patient's history and careful physical examination, sometimes accompanied by laboratory and imaging studies, leads to the diagnosis. A patient with hereditary hypertrophic osteoarthropathy and its clinical symptoms is presented. Surgical correction of the clubbing fingers is demonstrated in the paper with bilateral resection and shortening of the nail bed, nail matrix and resection of soft tissue. Clubbing fingers are rare, but they might be part of a syndrome or a symptom of other diseases. Reconstructive surgery for aesthetic reasons can be performed.

Abstract
Micro-computed tomography (muCT) is of great interest for palaeopathological examination because it is less invasive than histology. This study evaluates the diagnostic value of muCT for postcranial macerated bones. We investigated five specimens (osteomyelitis, tuberculosis, trauma, osteosarcoma and hypertrophic osteoarthropathy) of a pathology reference series by muCT and polarised light microscopy. The 3D muCT images allow an easy orientation within the specimen. Surface structures, thickness, continuity of the cortex and number, thickness and orientation of the trabeculae can be evaluated. The high number of muCT slices helps to choose the most interesting areas for further investigations. Grey value images display the degree of mineralisation. Yet, the differentiation between woven and lamellar bone is only possible using polarised light microscopy. muCT is a tool of high value for the examination of postcranial bone disorders. It cannot replace histological examinations completely because it cannot assess the bone quality (woven or lamellar). For the choice of the optimal location where slices for the microscopic investigation are later cut in heterogeneous samples, muCT is very useful. Therefore, we suggest performing the muCT examination first, followed by histology if necessary.

Abstract
Scleroderma en coup de sabre, a variant of localized scleroderma is a disorder characterized by fibrosis of connective tissue. We report a 21-year-old female with scleroderma en coup de sabre accompanied by pachydermoperiostosis. She was born to consanguineous parents and her older sister also had pachydermoperiostosis characterized by clubbing of the digits, enlargement of distal parts of the extremities. The two disorders were diagnosed by clinical examination, histological and x-ray findings. In contrast to scleroderma, pachydermoperiostosis is a hypertrophic process characterized by periosteal proliferation of the tubuler bones and hypertrophic skin changes. We discuss this interesting coexistence and review the literature.

Abstract
Pachydermoperiostosis or primary hypertrophic osteoarthropathy, also known as Touraine-Solente-Golé syndrome, is a rare process, frequently inherited. In its complete form it is characterized by pachydermia (thickening of the skin), skeletal changes (periostosis) and acropachia (digital clubbing). We report a patient that consulted for skeletal symptoms, as the acropachia and cutaneous manifestations (thickening of the skin of the face, scalp, hands and feet) went unnoticed due to their slow and progressive development. We review the characteristic features of this syndrome. We highlight the importance of ruling out secondary forms of hypertrophic osteoarthropathy and of a close follow-up of these patients because of complications that might develop on the long-term.

Abstract
Thymic lymphoepitheliomalike carcinoma (LELC) in children is extremely rare and we report 2 such cases with molecular analysis of Epstein-Barr virus (EBV) and its encoded latent membrane protein-1 as well as a literature review. Both of our patients were male, presented with a huge anterior mediastinal mass, expired within a year after diagnosis despite treatment. There were altogether 9 cases of thymic LELC in children. Their common clinical features include a male predominance, large tumor size, advanced clinical stage, and poor clinical outcome. All cases were associated with EBV and nearly half developed concurrent hypertrophic osteoarthropathy (HOA). Thymic LELC in children is an aggressive EBV-associated malignant tumor frequently accompanied by HOA. We proposed that EBV might play a role in the development of HOA through the interactions of latent membrane protein-1, vascular endothelial growth factor, and cyclooxygenases-2.

Abstract
In this report we describe a rare association of pachydermoperiostosis with protein-losing enteropathy (PLE) in a family of three brothers. The first brother had the complete form of pachydermoperiostosis along with PLE. The second brother had the 'forme fruste' of pachydermoperiostosis, with minimal skin changes, bony abnormalities and PLE, which was due to intestinal lymphangiectasia. The third brother had an incomplete form of pachydermoperiostosis without evidence of PLE. To our knowledge, the association of pachydermoperiostosis with PLE due to intestinal lymphangiectasia has not been reported previously.

Abstract
Pachydermoperiostosis or primary hypertrophic osteoarthropathy is a rare disease characterized by cutaneous and osteoarthicular involvement. We describe two patients with finger clubbing, watch crystal nails, bones thickenings, arthritis and different grades of skin affection, without other clinical manifestations. Both did not know of having relatives with the same alterations. Radiological studies of the affected areas showed periostosis. Because of normal laboratory results and chest radiography plus the absence of other underlying causes, diagnosis of primary hypertrophic osteoarthropathy was made.

Abstract
Pachydermoperiostosis (PDP) is a rare genodermatosis, characterized by pachydermia, digital clubbing, periostosis and an excess of affected males. Although an autosomal dominant model with incomplete penetrance and variable expression has been proved, both autosomal recessive and X-linked inheritance have been suggested. However, at present, genetic heterogeneity is not fully supported. The aim of this study is to review the clinical and pedigree data of 68 published PDP families, including 204 patients. This analysis has confirmed an autosomal dominant mutation in 37 families and suggested the existence of an autosomal recessive form in the remaining families. The two forms may differ in clinical severity, intrafamilial variability and prevalence of some features. Additionally, the marked skewed sex ratio could not be easily explained by an X-linked mutation, but alternative explanations (i.e. testosterone promoting proliferation) are discussed.

Abstract
OBJECTIVE To investigate the treatment and possible pathogenesis of pachydermoperiostosis. METHODS Facelift was performed on five patients with pachydermoperiostosis. Histological studies were performed to check the affected skin for possible pathogenesis. RESULTS After the surgery of facelift, appearances of the patients were markedly improved. Histological studies revealed significant changes in the skin, characterized by hyperplasia and thickening of the subcutaneous collagen, as well as an increase of PAS-positive substance. CONCLUSION Alterations of fibroblast bioactivity might be responsible for the pathogenesis of pachydermoperiostosis. There have been no satisfying treatments to the disease. Facelift is a feasible method to improve the aging appearance of the patients.

Abstract
INTRODUCTION Pachydermodactyly is a superficial fibromatosis located on the proximal portion of fingers'phalanges and interphalangeal joints. Several types of this disease have been described depending on topography, etiology and pathological associations. We report a typical observation of pachydermodactyly associated with a plantar pachydermy. CASE-REPORT A 19 year-old man was followed for a psychotic disease, associated with mental retardation. On clinical examination, he showed a typical pachydermodactyly, predominantly located on the second, third and fourth fingers of both hands, associated with recent acrocyanosis. A pachydermic aspect was also observed on the external part of the feet sole. Histopathological analysis was identical on digital and plantar lesions with collagen swelling. These lesions extended into the subcutaneous fat only in the feet. DISCUSSION This observation is compatible with the most classical form of pachydermodactyly which involves several fingers of both hands, usually in men. Furthermore, the association with a psychiatric disorder and the notion of repeated traumatisms have been frequently reported in the literature. However, acrocyanosis and the important disability observed in our case are unusual. Association with plantar pachydermy has never been reported. The identical histological aspect on finger and feet sole suggests that pachydermatodactyly should be integrated in framework of acral pachydermy.

Abstract
UNLABELLED Pulmonary epithelioid hemangioendothelioma is a rare vascular tumor of the lung, that may be revealed by hypertrophic pulmonary osteo-arthropathy. CASE REPORT A 15-year-old patient was admitted because of a 1-month history of pneumonia associated with clubbing. A hypertrophic pulmonary osteo-arthropathy due to a paraneoplastic syndrome associated with lung epithelioid hemangioendothelioma was diagnosed. Despite surgical resection and chemotherapy, the patient died 6 months later. COMMENTS Hypertrophic pulmonary osteo-arthropathy is a rare syndrome in childhood, and is frequently associated with chronic respiratory failure. Diagnosis is confirmed by long bones proliferative periostitis on standard X-ray examination. Pulmonary epithelioid hemangioendothelioma is a rare vascular malignant tumor, that spreads from the vascular pulmonary or hepatic tissues. The prognosis is variable, depending on the malignancy of the tumor. In the absence of a chronic cardiorespiratory disease, the diagnosis of a pulmonary hypertrophic osteo-arthropathy in childhood should prompt the search for a tumoral cause.

We report a case of a family with a variant form of primary hypertrophic osteoarthropathy (HOA) restricted to the lower extremities without digital clubbing or cutaneous changes. Three family members suffered from pain, swelling and hyperhidrosis of both feet. X-rays showed destruction and osteoproliferative changes of the metatarsal bones with periostal hyperostosis close to the talus. There was an increased 99m-Tc-MDP uptake in the early phase of bone scintigraphy. Fibrosis of the marrow with stimulated osteoclastic resorption and the presence of detritus synovialitis were visible in a bone and joint biopsy. All known infectious, neurologic, metabolic and malignant diseases, which affect the bone and joints, were excluded.

Abstract
INTRODUCTION The finger clubbing is most of the time associated with cardiovascular and pulmonary diseases. Pachydermoperiostosis also known as osteodermopathic syndrome, an hereditary disorder, is a rare cause of finger clubbing which might be difficult to diagnose in an incomplete form. EXEGESIS We report a 36 years old black man presenting over many years polyarthralgias, broadening of fingers and clubbing of the fingers and toes extremities. This was mentioned on other family members. The physical examination was otherwise unremarkable. There were no skin thickening, no psoriasis-like and cardio-pulmonary disease features. These following exams were normal; Hemogram, fibrinogen, C reactive protein, rheumatoïd factor, serum calcium and phosphorus, thyroid hormones, growth hormone, chest X-ray, gastroduodenoscopy, electrocardiogram. The skeletal X-ray documented a widespread bone formation, a sacro-iliac osteosclerosis and interosseous ossifications betwen tibias and fibulas. CONCLUSION Pachydermoperiostosis diagnosis was set up on 3 out of the 4 Borochowitz criteria. The absence of pachyderma defines this incomplete form. The osteoarticular manifestations lead mainly to differential diagnosis with the secondary hypertrophic osteoarthropathy and chronic inflammatory rheumatisms. The underlying pathogenic mechanism of this disease remains still unclear.

Abstract
Two different vaccination protocols were compared with regard to the development of hypertrophic osteodystrophy (HOD) (also termed metaphyseal osteopathy) and effectiveness of immunisation in a litter of 10 Weimaraner puppies. Five puppies (group 1) were vaccinated with a modified live canine parvovirus vaccine (CPV) and then two weeks later with a trivalent vaccine containing modified live canine distemper virus and adenovirus type 2 combined with a Leptospira bacterin (DHL). The CPV and DHL vaccine protocols were administered a further two times, at two-week intervals. Group 2 was vaccinated with three consecutive multivalent vaccines containing modified live canine distemper virus, canine parvovirus, parainfluenza and adenovirus type 2 combined with a Leptospira bacterin, at four-week intervals. All puppies were first vaccinated at the age of eight weeks. Three dogs in group 1 developed HOD, while all five dogs in group 2 developed HOD during the study period. Dogs in group 2 had more episodes of HOD than those in group 1. Dogs in group 1 developed higher antibody titres to canine distemper virus and parvovirus compared with those in group 2. Only two out of the 10 dogs developed protective antibody titres to parvovirus. The results of this study suggest that the two different vaccination protocols affected the pattern of appearance of HOD and immunisation in this litter of Weimaraner puppies. The results obtained and the previously reported data suggest that a larger controlled study is needed to further elucidate the effect of different vaccination protocols on HOD and immunisation in Weimaraner puppies.

BACKGROUND Our aim was to establish clinical and imaging characteristics of primary hypertrophic osteoarthropathy (PHO). METHODS A group of 76 patients (71 men and 5 women) with primary hypertrophic osteoarthropathy was examined. Extensive history and status of the locomotor system were determined in all patients. Radiologic and scintigraphic examinations of the bones, thermography, capillaroscopy, gastroscopy, and histologic analysis were also performed. RESULTS Family history was positive in all 55 patients (100%) summoned for a check-up. Finger clubbing of the hands and feet as well as positive Schamroth test were found in all patients, while hyperhydrosis was found in 65 (85.5%), seborrhea in 39 (51%), and involvement of the joints in 52 (68.5%) patients. Histologic analysis in 18 (23.7%) patients predominantly showed periarticular edema and moderate cellular activity. Periostosis of the long bones was also found in all patients, while scintigraphy, performed in 44 patients, was positive in 18 (33.5%) patients in the active phase of the disease. Thermography, performed in 10 patients, ranged from hypothermia to thermal amputation of feet and hands. Capillaroscopy of hands and feet in 47 (61.8%) patients showed changes in small blood vessels. Gastroscopy indicated abnormalities (ulcer and hypertrophic gastritis) in 21 patients (27.6%). CONCLUSIONS PHO has special clinical and radiographic manifestations (finger clubbing and periostosis of the long bones) that are associated with some minor manifestations. Development of the disease is gradual (to 20 years) and requires a special diagnostic assessment.

Abstract
Thymic carcinoma is exceptionally rare in children and it has never previously been associated with autoimmune disorders. The authors report the case of an 11-year-old boy with thymic carcinoma, hypertrophic pulmonary osteoarthropathy, and an autoimmune disease that resembled systemic lupus erythematosus. To their knowledge, this is the first case of such complex clinical findings. The tumor was of high grade histologically and the boy died after 1 year, in spite of chemotherapy and radiotherapy. A review is presented of the available medical literature on thymic malignancy in childhood.

Abstract
Pachydermoperiostosis (PDP), a rare genodermatosis, occurred in a 38-year-old Indian male. He presented with progressive thickening of the skin on the face and scalp of 15 years duration. Widening of his wrists and ankles and broadening of the fingers and toes had also developed since then. He was born of a consanguineous marriage and had no family history of a similar disorder. He had the typical findings of complete form of PDP including cutis verticis gyrata, coarse facial features, clubbing of the digits in the skin, and periostosis and cortical thickening at the distal ends of long bones of the extremities and small bones of the hands and feet. PDP has two different forms--primary and secondary. These two entities are differentiated by family history and presence or absence of a primary lesion, usually in the lungs. Clinically, in secondary PDP, the cutaneous findings (pachydermia, seborrhoea, oiliness) are less severe than primary PDP; osteoarthropathy is more severe and painful in secondary PDP, especially with congenital heart disease. The present case was suffering from primary PDP that had expressed itself in its complete form.

Abstract
PURPOSE Pachydermoperiostosis, or primary hypertrophic osteoarthropathy, is a rare disease, characterized by pachydermia, acropathy, and periostosis. The authors propose the surgical correction of the eyelid anomalies in one stage. METHODS A 30-year-old patient with moderate blepharoptosis (3 mm) and increased vertical and horizontal dimensions of the upper eyelids underwent fusiform transverse excision of skin, orbicularis muscle, and tarsus; shortening of the levator palpebrae superioris apeoneurosis by 13 mm; and 8-mm-wide wedge excision. RESULTS Histologic findings included hyperplasia of the tarso-conjunctival plate, obstructive cystic dilatation of the sebaceous glands, extensive fibrosis, and granulomatous reaction. Satisfactory functional and aesthetic results were observed after surgery. CONCLUSION Upper eyelid anomalies in pachydermoperiostosis can be corrected in a single stage bilaterally with good results.

Abstract
OBJECTIVE To characterize hypertrophic osteoarthropathy (HOA) in skeletons to allow its recognition in the archeologic record. METHODS Individuals diagnosed in life with diseases known to cause HOA were examined from the Hamman-Todd, Grant, and Terry human skeletal collections. The latter consist of 5142 individuals who died in the early part of this century. A "control" group was obtained by examination of 100 (consecutive, exclusive of HOA related disorders) additional individuals from the Terry Collection, which were accompanied by diagnoses not known to be associated with HOA. Sixty individuals documented with skeletal evidence of syphilis (from the Hamman-Todd Collection) and 73 individuals documented as having skeletal evidence of yaws (from the Ward Site, 4300 ybp) were examined as comparison treponemal disease-derived, periosteal reaction-afflicted populations. RESULTS In total, 319 individuals were identified with HOA. HOA was recognized as a disorder of distal diaphyseal or diffuse periosteal reaction. Proximally-limited disease virtually eliminates the diagnosis. CONCLUSION HOA is recognizable as a population phenomenon suggestive, when found in the archeologic record, of underlying chronic pulmonary disease.

Abstract
Hypertrophic osteoarthropathy is characterized by digital clubbing, arthropathy and periostosis of long tubular bones. Currarino's disease is an extremely rare variant of primary hypertrophic osteoarthropathy in which there is delayed closure of the fontanelles and an absence of skin involvement. Most reported cases have been in blacks. We report a case in a Caucasian adolescent.

Abstract
A 4.5-yr-old female blesbok (Damaliscus dorcas phillipsi) was radiographed following the appearance of lameness and swelling of the right front fetlock. Radiographic interpretation at that time was osteoarthritis caused by periosteal proliferation of the right metacarpus with periarticular osteophytes surrounding the fetlock. No treatment was initiated. Gradual abdominal enlargement over several months was interpreted as evidence of pregnancy. Six months after the initial lameness complaint, the blesbok suddenly collapsed and was unable to stand. Physical examination revealed a large firm mass occupying most of the abdomen that was found to be inoperable. Following exploratory laporotomy, the blesbok was euthanized. At necropsy, the mass weighed 17 kg. It had probably caused the animal's collapse. Histologically, the bony lesions of the right metacarpus, seen radiographically at the previous examination, were consistent with hypertrophic osteoarthropathy and may have been a sequela of the intra-abdominal mass.

Abstract
Few syndromic associations with Crohn's disease are described. The aim of this study was to characterize a new syndrome of Crohn's disease associated with pachydermoperiostosis in 3 brothers. Three probands, 6 siblings, both parents, 20 of 21 third-generation relatives, and 9 spousal controls were evaluated. Serological evaluation for antineutrophil cytoplasmic antibodies and human leukocyte antigens as well as genetic testing for tumor necrosis factor microsatellites, intercellular adhesion molecule 1 polymorphisms, the interleukin 1 receptor antagonist gene, and the interleukin 1 beta gene were performed. Only the 3 probands were affected and developed pachydermoperiostosis between ages 14 and 17 years. Pachydermoperiostosis preceded Crohn's ileocolitis by 6 and 20 years in two probands, excluding secondary hypertrophic osteoarthropathy. Two probands were antineutrophil cytoplasmic antibody positive vs. 1 of 27 unaffected relatives (P < 0.001, chi 2). Haplotypes for human leukocyte antigen and tumor necrosis factor microsatellites were discordant. The probands' generation was homozygous for the common allele 1 of the interleukin 1 receptor antagonist and interleukin 1 beta genes. Two probands carried a rare polymorphism of the intercellular adhesion molecule 1 gene. A new syndrome of Crohn's disease and pachydermoperiostosis associated with antineutrophil cytoplasmic antibodies is described. Inheritance is most likely autosomal recessive by pedigree. No clear association was found between this syndrome and the gene regions evaluated.

Abstract
BACKGROUND Joint and nail involvement in psoriasis is relatively common. In contrast, bony involvement of the terminal phalanx under a psoriatic nail is rare. We report on this psoriatic onycho-pachydermo-periostitis and suggest pathophysiologic mechanisms. OBSERVATIONS Two new cases are reported and the data are compared with the data from eight similar cases reported in the literature. All subjects presented with similar changes--onychopathy, soft-tissue thickening, and radiologic features consisting of bone erosions and a periosteal reaction of the terminal phalanx. Of the 10 patients, two had no history of psoriasis before a diagnosis of psoriatic onycho-pachydermoperiostitis was made. The inflammation is likely transmitted from the psoriatic nail to the adjacent underlying bone by the same mechanism as in enthesopathies. CONCLUSION Psoriatic onycho-pachydermo-periostitis should be recognized as a specific entity in the spectrum of psoriatic disease.

Abstract
Pachydermoperiostosis (primary hypertrophic osteoarthropathy) is a very rare genetic disease characterized by pachydermia, periostosis, arthralgia, and finger clubbing. Its pathophysiology is still unclear, but previous studies have reported connective tissue hypertrophy in the skin of these patients. We investigated the synthesis of collagen, fibronectin, and proteoglycans by fibroblasts from affected and unaffected skin from one patient with pachydermoperiostosis and four normal donors. We found that collagen synthesis was largely decreased in fibroblasts from the diseased skin, whereas the synthesis of the small dermatan-sulfate-containing proteoglycan decorin strongly increased. Fibroblasts from the unaffected skin of the patient exhibited syntheses of these macromolecules similar to control fibroblasts from healthy donors. Northern blot and dot blot analyses showed decreased pro alpha 1 (I) collagen in patient's affected and unaffected skin fibroblasts whereas increased decorin mRNA levels were found in fibroblasts from the patient's affected skin. No change in cell proliferation was observed. These data demonstrate an alteration of fibroblast biosynthetic activity in the skin lesions of pachydermoperiostosis, which may be responsible, at least in part, for the patient's phenotype.

Abstract
Pachydermoperiostosis or primary hypertrophic osteoarthropathy (HOA) is a rare congenital growth disorder of connective tissue. We report a case of severe myelofibrosis in a patient with HOA. When cultured in vitro, patient bone marrow-derived fibroblasts displayed a high proliferative potential with a shortened doubling time (24 hours v 36 to 48 hours for normal fibroblasts). The role of platelet-derived growth factor (PDGF), previously implicated in the pathogenesis of secondary acquired myelofibrosis, was studied. HOA fibroblasts expressed an increased number of PDGF-BB binding sites (300,000 sites/cell v 200,000 sites/cell for normal fibroblasts) without any modification of affinity. The increased expression of PDGF-R beta appeared to result from an accelerated rate of PDGF-R beta resynthesis with normal kinetics of endocytosis. As a consequence, a several-fold increase of PDGF-R beta tyrosine kinase activity was observed. No autocrine mechanism of growth was suspected as neither spontaneous PDGF-R beta autophosphorylation nor mitogenic activity in HOA fibroblast-conditioned medium was detected. Patient serum and platelet lysate were less potent than controls in inducing [3H]thymidine incorporation into HOA fibroblasts. This was inconsistent with a paracrine mechanism of growth. In vitro, human serum or PDGF-BB were not more mitogenic for HOA than normal fibroblasts. High levels of cyclin D1, a putative oncogene, were detected in serum-deprived HOA fibroblasts. Cyclin D1 overexpression could be implicated in the accelerated growth of these cells. Our results suggest that the mechanism of fibroblastic proliferation observed in this case of myelofibrosis might differ from those reported in other acquired myeloproliferative syndromes and could be associated with an intrinsic abnormality of HOA fibroblast growth.

Abstract
Pachydermoperiostosis (Friedreich-Erb-Arnold syndrome, Touraine-Solente-Golé syndrome) is a rare disease with an autosomal dominant mode of inheritance; it occurs almost exclusively in men. A report of typical pachydermoperiostosis in a 31-year-old man is presented. Associated features were clubbed digits of the hands and feet with watch-crystal nails, thickening of the skin and soft tissues, hyperhidrosis of hands and feet, hyperplasia of the sebaceous glands with seborrhoea, gynaecomastia, and ophthalmic abnormalities that had been present since puberty. Radiological examination revealed periosteal hyperostosis of the short and long bones. Endocrine disturbances were not detected. Skin biopsies showed hypertrophy of the skin and skin appendages. Primary (idiopathic, hereditary) pachydermoperiostosis should be distinguished from secondary (symptomatic) forms of the disease, which are often associated with lung tumours.

Abstract
Pachydermoperiostosis (PDP) is a hereditary disease with hyperostosis, clubbing of fingers, coarse skin and thickening of bones. Previous studies have disclosed some abnormality in the connective tissue in these patients. The purpose of the present study was to investigate connective tissue pathology in one family with PDP using fibroblast cultures. Fibroblastic cells were established from both the affected and healthy looking skin of 2 patients with PDP, and the expression of types I and III collagen, 92 kDa and 72 kDa gelatinases, metalloproteinase inhibitor (TIMP-1), human retinoic acid receptor and transforming growth factor beta (TGF beta) was analyzed. The modulation of glycoprotein synthesis, and of plasminogen activators and their inhibitors by TGF beta in vitro were also studied. The results indicated that collagen genes and gelatinases were similarly expressed in PDP and control cells, as well as the human retinoic acid receptor. TGF beta stimulated, both in PDP cells and normal cells, the synthesis of fibronectin, procollagen and plasminogen activator inhibitor-l (PAI-1), but qualitative differences could not be found. Proteolytically processed forms of PAI-1 were detected in PDP cell lines.

Abstract
A thirteen year-old boy with progressive enlargement of the joints and distal extremities, clubbing, coarse facial features and hyperhidrosis was investigated. His endocrine profile was normal. Radiological studies demonstrated bilateral symmetrical periosteal new bone formation with acroosteolysis. After extensive investigation to exclude systemic and endocrine causes, a diagnosis of pachydermoperiostosis was made. Awareness of this condition helps to differentiate this syndrome from pulmonary osteoarthropathy and acromegaly.

Abstract
BACKGROUND Pachydermoperiostosis (PDP) is a rare hereditary disease characterized by hyperostosis, clubbing of fingers, coarse skin, and abnormalities in other organs, such as the gastrointestinal tract. Previous studies have disclosed several abnormalities in the connective tissue in these patients. OBJECTIVE The purpose of the study was to investigate connective tissue abnormalities in one family with PDP. METHODS Clinical features were evaluated; x-ray, immunohistochemical, and electronmicroscopic studies were performed; and markers of collagen metabolism and lysosomal enzymes were determined. RESULTS Immunohistochemical and ultrastructural studies revealed accumulation of tenascin, glycosaminoglycans, and fibrillar material in apparently disorganized microfibrils of elastic fibers. Osteocalcin levels in the serum were increased, but synthesis and degradation markers of collagen in the serum were not altered. No evidence of a lysosomal enzyme deficiency was found. CONCLUSION Acidic mucopolysaccharides and some fibrillar material accumulate in the dermis of patients with PDP. Increased levels of osteocalcin in serum indicate higher osteoblastic activity. Markers of synthesis and degradation of collagen were not altered.

Abstract
OBJECTIVE To investigate collagen synthesis in skin fibroblasts from patients with primary hypertrophic osteoarthropathy (HOA), a disorder characterized clinically by skin thickening. METHODS Collagenase-digestible protein, messenger RNA (mRNA) levels, and transcriptional activity of the alpha 1(I) procollagen gene were assessed in skin-derived fibroblast lines. RESULTS Compared with fibroblasts from uninvolved skin, fibroblasts from involved skin had elevated levels of collagen synthesis and alpha 1(I) procollagen mRNA, and increased transcriptional activity of the alpha 1(I) procollagen promoter. CONCLUSION Abnormalities of collagen synthesis in fibroblasts from patients with primary HOA can be accounted for, at least in part, by a trans-activated up-regulation of collagen transcription.

Abstract
Benign soft tissue swelling affecting the interphalangeal joints can sometimes be misdiagnosed as an arthropathy. Garrods fatty pads (knuckle pad syndrome) is a relatively common and harmless condition characterized by discrete fibromatous skin pads over the dorsum of the interphalangeal joints. We describe a case which clinically resembles the rare but benign condition of pachydermodactyly with some pathological features of the distinct syndrome of pachydermoperiostosis. The possibility of an overlap syndrome is discussed.

Abstract
Hypertrophic osteoarthropathy is one of the earliest recognized disease entities in the history of medicine. It has a peculiar periosteal proliferation distinctive from other bone diseases. In its advanced stage, it leaves an indelible mark on the skeleton. It has been recently shown that digital clubbing is accompanied by a bone remodeling process of the underlying phalanges. Thus, theoretically, this entity can be recognized in ancient human skeletal remains. We studied part of the collection of skeletal remains from pre-Hispanic Mesoamerica preserved at the National Museum of Anthropology of Mexico City. We examined 1000 specimens and found 2 skeletons with widespread, bilateral, symmetric periosteal proliferation of the tubular bones in addition to the bone remodeling changes of the distal phalanges. One of the specimens was from the Formative period (2000 B.C. to 100 A.D.). We conclude that hypertrophic osteoarthropathy can be recognized in ancient human skeletal remains and that this disease was present in Mesoamerica near the time of the original description of clubbing by Hippocrates about 2500 years ago.
