Immunohistochemistry in Primary B-cell Lymphoma of Tibia Masquerading as Chronic Osteomyelitis.

The diagnosis between chronic osteomyelitis, Ewing sarcoma and lymphoma often is being confusing in many occasions. As the latter two conditions are malignant, early diagnosis and interventions are crucial. We present a 28 year old male with features of chronic osteomyelitis of right tibia 2 years back then changed through Ewing sarcoma to B-cell lymphoma in the histological diagnosis. This case report highlights the difficulties that arise in diagnosing primary bone lymphomas which may masquerade as chronic osteomyelitis and hence the need for immunohistochemistry in chronic recurrent osteomyelitis.

Case report: congenital dislocation of the radial head -a two-in-one approach.

BACKGROUND: Congenital dislocation of the radial head of the elbow is rare. It is genetically transmitted in some cases and is often associated with syndromes, such as Nail-Patella syndrome, antecubital pterygium and ulnar dysplasia. About two thirds are posterior, with the remainder being either anterior (15%) or lateral (15%). The natural history of the condition is that symptoms are relatively benign, with only some limitation of motion and deformity. Treatment either involves early attempts at reconstruction or delayed intervention at skeletal maturity with radial head excision. We evaluated the radiographic and functional results of a two-in-one procedure (radial shortening and open reduction) in the treatment of congenital dislocation of the radial head of an eight year old girl. OBJECTIVE: To describe a technique for easy reduction and maintenance of normal radiocapitellar joint anatomy in cases of congenital dislocation of the radial head. METHOD: We have introduced one modification to the Sachar's method of open reduction by adding radial shortening. This can be described as a 'two incision approach' with the first incision for the radial shortening and the second for the open reduction of the radiocapitellar joint. The radial shaft was osteotomised first before we performed the radial head relocation. Then the overlapping part of radial shaft was trimmed. It was stabilized with a transarticular K wire fixation. RESULTS: At one year follow up, the elbow is stable with no valgus or fixed flexion deformity. Supination has increased to 40 degrees from zero degrees. An X-ray showed reformation of the radial head with good congruity of the radiocapitellar joint and correction of the radial bow. CONCLUSION: As far as the authors are aware, this is the first report of congenital dislocation of the radial head being treated by radial shortening and open reduction of radiocapitellar joint through a two incision approach (two-in-one approach). This paper describes this new technique, which we implemented for easy reduction maintenance of normal radiocapitellar joint anatomy.

Tibial osteomyelitis due to Fonsecaea pedrosoi in an immunocompetent patient: case report.

UNLABELLED: Dematiaceous fungi are the etiological agents of phaeohyphomycosis. Diverse presentations of infectious syndromes are seen, ranging from local infections after trauma to widely disseminated infection in immunocompromised patients. Fonsecaea pedrosoi species have been reported to cause an increasing number of infections, particularly in severely immunocompromised patients. Colonization of normal skin has been reported. We present a case of F. pedrosoi osteomyelitis in an immunocompetent patient. A high level of suspicion and routine fungal cultures are required to identify these cases. Tissue culture and pathologic examination are necessary for definitive diagnosis and for distinguishing infection from colonization. Therapy includes antifungal drugs (itraconazole) and aggressive surgical debridement, and, even when these modalities are readily implemented, the outcome may not be optimal because of the angioinvasive character of the organism. LEVEL OF CLINICAL EVIDENCE: 4.

Servelle-Martorell syndrome with extensive upper limb involvement: a case report.

INTRODUCTION: Angio-osteohypotrophic syndrome is also known as Servelle-Martorell angiodysplasia. It is characterized by venous or, rarely, arterial malformations, which may result in limb hypertrophy and bony hypoplasia. Extensive involvement of the upper limb is a rare feature of Servelle-Martorell syndrome. Cases with minimal upper limb involvement have been described in the literature. CASE PRESENTATION: A young man presented with multiple separate swollen areas over the right upper limb and functional difficulty since birth. The arm muscles and muscles of the limb girdle were atrophic. The forearm and hand bones were hypoplastic and tender. CONCLUSION: We report a case of Servelle-Martorell syndrome with extensive involvement of the entire upper limb and periscapular region. Servelle-Martorell syndrome is highlighted as one of the causes of angiodysplastic limb hypertrophy.
