We report three patients with lateral ankle and foot pain, with the diagnosis of stenosing tenosynovitis of the peroneus longus tendon associated with a markedly enlarged peroneal tubercle. Stenosing tenosynovitis of the peroneus longus tendon associated with an atraumatically enlarged peroneal tubercle has rarely been reported, and these reported cases were associated with an os peroneum. One of our patients had no demonstrable associated os peroneum but did have a bony tunnel enveloping the peroneus longus tendon. Our other two patients had an os peroneum, but were asymptomatic at the lateral outer border of the cuboid tunnel; one patient had involvement of the peroneus longus and brevis tendons.

To date no prosthetic vascular prosthesis performs as well as autologous conduits for small diameter arterial reconstruction. We report the outcome of our first case using a new vascular prosthesis marketed by Cryolife, the SynerGraft. This Xenograft prostheses is claimed to eliminate the problems of the previous generation of gluteraldehyde treated grafts. Two 50 cm SynnerGrafts were anastomosed end to end and used as a femoral-posterior tibial bypass graft in a 68-year-old man who presented with an acutely ischaemic left leg. Our patient represented at 8 weeks with aneurysmal degeneration along the course of the graft. We urge caution in the use of these grafts until convincing data in humans is presented.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a distinct type of peripheral T-cell lymphoma, which has gained recognition over the past decade. The disease presents complex clinical, pathologic, and immunohistochemical features, which warrant awareness by dermatologists, dermatopathologists, hematopathologists, hematologists, oncologists, and internists. SPTCL was initially included as a provisional entity in the Revised European-American Lymphoma classification, followed by the European Organization for Research and Treatment of Cancer classification as a primary cutaneous lymphoma, and subsequently as a distinct entity by the World Health Organization classification. It is known that patients diagnosed with SPTCL usually respond poorly to therapy, and the tumor progresses aggressively. Data from recent studies in a series of cases of SPTCL by the European Organization for Research and Treatment of Cancer Cutaneous Lymphoma Group have further identified SPTCL as a heterogeneous disease entity, which comprises an alpha/beta subtype (SPTCL-AB) and a gamma/delta subtype (SPTCL-GD). The latter has recently been included in the entity of "cutaneous gamma/delta T-cell lymphoma" by the World Health Organization, Pathology and Genetics of Skin Tumours. The clinical, histologic, and immunophenotypic data, treatment, and prognosis, appear different in the 2 subtypes of SPTCL. We report a case of fatal SPTCL-GD (cutaneous gamma/delta T-cell lymphoma), with detailed clinicopathologic features, immunohistochemical studies, treatment, and clinical course. In view of its aggressive behavior, identification of this disease is critical for proper management and treatment.

These results demonstrate and provide methodologies for labeling, detecting, and extracting MRI-detectable foci of iron-labeled cells.

A 64-year-old male renal transplant recipient developed rectal bleeding caused by a primary lymphoma of the colon, an unusual site for initial disease involvement. Renal transplant recipients may be at increased risk for the development of primary colonic lymphoma, a diagnosis that should be considered in transplant patients who develop abdominal pain, rectal bleeding, or intestinal perforation. The unique clinical features and special management considerations of colonic lymphoma in the renal transplant recipient are discussed.
