Primary malignant non-Hodgkin lymphoma of the talus: a case report

Metastasis of Cutaneous B-Cell Lymphoma Affecting the Metatarsal Head: A Case Report

There are few reported cases of non-Hodgkin's lymphoma metastasis to bone in the lower extremities. The authors present a case of cutaneous B-cell lymphoma thought to be in remission, with metastasis to the first metatarsal head with involvement in the synovial tissue of the first metatarsophalangeal joint. Following excision of the lesion, no further treatment was determined to be necessary. The patient was to be observed for local recurrence.

Primary bone lymphoma of the talus: a challenging diagnosis

PURPOSE

Diagnostic challenges are common in clinical practice and diagnostic or classification criteria for musculoskeletal conditions cannot overshadow clinical skills.

METHODS

We present the case of a young man who complained of prolonged articular pain and mild swelling of the right ankle in the absence of other remarkable data. Apparently fulfilling the Budapest diagnostic criteria for complex regional pain syndrome, the patient was treated accordingly, but the pain increased over time. Then the patient underwent an additional diagnostic workup including synovial and bone biopsies in 2 separate occasions with the second one demonstrating diffuse lymphoid infiltrate compatible with lymphoma.

RESULTS

The conclusive diagnosis of primary diffuse large B-cell lymphoma of the talus was made and adequate treatment initiated.

CONCLUSIONS

The diagnostic difficulties as well as the importance of a multidisciplinary approach for complex cases are highlighted in this report.

Primary malignant lymphoma of the talus: A case report and review of the literature

Malignant lymphoma commonly occurs in adults, with a peak incidence between the seventh and ninth decades of life. Although malignant lymphoma usually occurs in the lymph nodes, it rarely occurs primarily in the bone. We herein describe an extremely rare case of primary malignant lymphoma of the talus in a 74-year-old man. Although plain radiographs showed no abnormality, gadolinium-enhanced magnetic resonance imaging (MRI) revealed a well-circumscribed intra- and extraosseous tumor of the talus. ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/MRI revealed a marked increase of FDG uptake in the right ankle and the right inguinal lymph nodes. As the tumor was diagnosed as diffuse large B-cell lymphoma by core needle biopsy, combination therapy with chemo- and radiotherapy was initiated. The patient achieved complete remission, with no sign of recurrence at 8 months after initial chemoradiotherapy. Since primary malignant lymphoma of the bone is chemo- and radiosensitive and has a good prognosis, accurate staging by radiological investigation as well as correct pathological diagnosis by biopsy are required for optimal treatment.

Imaging findings of various talus bone tumors-clinico-radiologic features of talus bone tumors

Osseous neoplasms of the foot are uncommon, accounting for only 3.3% of all primary bone tumors. Bone tumors of the talus are even rarer, and there are not many publications that comprehensively evaluate the imaging findings of talus tumors. The purpose of this article is to review the benign and malignant bone tumors affecting this uncommon site and to describe the clinical and radiologic features of each tumor.

A Rare Presentation of Transformed, CD30(+) High-Grade Cutaneous T-Cell Lymphoma of the Hallux A Case Report

Cutaneous T-cell lymphoma is a type of non-Hodgkin's lymphoma, which is a neoplasm affecting the lymphatic system. Mycosis fungoides is the most common subset of cutaneous T-cell lymphoma and is often treated conservatively. This neoplasm is most common in adults older than 60 years and does not regularly manifest in the toes. A case is reported of a 70-year-old man seen for a nonhealing hallux ulceration leading to amputation. Histopathologic examination revealed a rare transformed CD30(+) high-grade cutaneous T-cell lymphoma. The morbidity of lymphomas is highly dependent on type and grade. Pharmaceutical precision therapies exist that target specific molecular defects or abnormally expressed genes, such as high expression of CD30. This article focuses on treatment protocol and emphasizes the importance of early diagnosis, determination of cell type, and proper referral of atypical dermatologic lesions.

Primary non Hodgkin's lymphoma of talus in a child-a rare presentation

We report a rare case of primary non-Hodgkin's lymphoma of bone which presented with an osteolytic lesion of the head of the right talus which to the best of our knowledge is the first case to be reported in the paediatric age group. Early and accurate identification is necessary as it has a good prognosis.

Incidental pedal manifestation of primary bone lymphoma: a case report

Primary lymphoma of bone (PLB) is an uncommon entity and is extremely rare in the foot and ankle. In this case, PLB was identified from the bone specimen after a bunionectomy of the first and fifth metatarsals. The diagnosis was confirmed with pathologic analysis, genetic karyotyping, positron emission and computed tomography scans, and fluorescence in situ hybridization (FISH). We felt that reporting this case was essential due to the rarity of its pedal occurrence and the lack of preoperative signs or symptoms.

Cutaneous non-Hodgkin's lymphoma of the foot: a rare case report

Lymphomas comprise a heterogeneous group of cancers originating in cells of the immune system at different stages of differentiation. Primary cutaneous non-Hodgkin lymphoma of the foot is a rare occurrence. We present a case involving a primary cutaneous marginal zone lymphoma of the foot, and highlight the clinical recognition and treatment of this condition.

Metastatic bone involvement of the hallux distal phalanx and cuboid in an elderly patient with non-Hodgkin lymphoma

Non-Hodgkin lymphoma metastasis to bone is a rare occurrence in the lower extremity. There have been very few reported cases. Bone metastasis, when it occurs, usually affects the axial skeleton. This article presents a case of Waldenström macroglobulinemia, a variant of non-Hodgkin lymphoma, with metastasis to the right hallux distal phalanx and left cuboid, as well as cutaneous lesions of the right foot. The patient received radiation treatments to each involved area with complete resolution of symptoms and tumor.

Osteonecrosis in the foot

Osteonecrosis, also referred to as avascular necrosis, refers to the death of cells within bone caused by a lack of circulation. It has been documented in bones throughout the body. In the foot, osteonecrosis is most commonly seen in the talus, the first and second metatarsals, and the navicular. Although uncommon, osteonecrosis has been documented in almost every bone of the foot and therefore should be considered in the differential diagnosis when evaluating both adult and pediatric foot pain. Osteonecrosis is associated with many foot problems, including fractures of the talar neck and navicular as well as Kohler's disease and Freiberg's disease. Orthopaedists who manage foot disorders will at some point likely be faced with the challenges associated with patients with osteonecrosis of the foot. Because this disease can masquerade as many other pathologies, physicians should be aware of the etiology, presentation, and treatment options for osteonecrosis in the foot.
