[Thésaurus Mesh]ThérapeutiqueRésumé : Background: Kaposi sarcoma (KS) has multiple clinical variants, and most frequently presents on the lower extremities. Anti–human immunodeficiency virus (HIV) therapy has significantly reduced the incidence of KS. However, KS is still prevalent in both HIV-infected and HIV-uninfected patients. This case series analysis aims to reveal the clinical presentations, differential diagnosis, and treatment options of KS on the foot and ankle.
Methods: Eleven cases of KS involving the foot and ankle were retrieved from our patient database, and their clinicopathologic features were analyzed.
Results: All patients were men, aged 29 to 85 years. Two types of KS were found: classic and acquired immunodeficiency syndrome–associated epidemic. The average ages of classic and epidemic KS were 65.7 and 41.8 years, respectively. Clinically, three patients manifested multiple erythematous or deep violaceous, or blue-violaceous macules on either the dorsal or plantar surfaces of both feet. Eight patients showed exophytic, pyogenic granuloma-like nodules on the plantar surface, heels, and toes. Histologically, all KSs had uniform intervening fascicles of elongated spindle cells with slit-like vascular spaces filled with red blood cells and immunoreactivity with human herpesvirus-8. The patients were treated according to HIV infection status. Human immunodeficiency virus–infected patients were treated with anti-HIV therapy after primary surgical excision or biopsy. Human immunodeficiency virus–negative patients were treated with either surgical excision, Mohs surgery, or a combination of surgical excision and local radiotherapy according to individual patient clinical presentation.
Conclusions: Kaposi sarcoma is still prevalent in both HIV-infected and HIV-uninfected patients with a variety of clinical presentations. Biopsy, with histologic evaluation, in combination with immunohistochemistry is essential for the differential diagnosis. The patient should be treated according their clinical manifestation, staging, comorbidity, and immune function.

[Thésaurus HELB]:Paramédical:Cas cliniqueMots-clés : Lymphome cutané diffus primaire à grandes cellules B Résumé : Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT) is a rare variant of the cutaneous B-cell lymphomas, with rapid growth and poor prognosis. Here, we report a case of PCDLBCL-LT on the foot in a senior woman. An 81-year-old woman presented with a rapidly growing mass on her left foot, and discoloration in both lower legs over the past 2 months was analyzed. Physical examination revealed hyperpigmented macules and papules on both lower extremities and a 3.0 2.0 0.5-cm, gray-dark nodule on the dorsal surface of the left foot. Histologic observation of the punch biopsy specimen revealed a sheet of atypical large centroblast/immunoblast-like lymphocytes; diffusely and evenly distributed in the dermis; with the immunophenotypes of CD45-positive, CD20-positive, Melan A-negative, Sox10-negative, S-100–negative, and CK20-negative; and a very high Ki-67 proliferative index (.90%). Further punch biopsy specimens of papules in the patient’s lower extremities and bone marrow did not reveal atypical lymphoid tissues. Positron emission tomography/ computed tomography did not show any metastatic lesions in distant organs and lymph nodes. The lesion was diagnosed as PCDLBCL-LT stage T1N0M0. The patient was treated with four cycles of combined therapy of rituximab and cyclophosphamide, hydroxydaunorubicin, vincristine (Oncovin), and prednisolone and the tumor was further treated with local radiotherapy. The tumor size was significantly shrunken. Primary cutaneous diffuse large Bcell lymphoma, leg type is a rare entity on the foot, characterized by a confluent sheet of diffuse large centroblast- and or immunoblast-like B cells with B-cell immunophenotyping. The combined therapy of rituximab and cyclophosphamide, hydroxydaunorubicin, vincristine (Oncovin), and prednisolone is the first-line treatment regimen, with increased survival.

[Thésaurus Mesh]Présentations de casRésumé : Soft-tissue chondroma is a rare, benign tumor. It is predominantly found in the hands and feet, but rarely in the toes. In this article, we report a digital soft-tissue chondroma that presented as a painful nodule of 5 years' duration in a 67-year-old man. Physical examination revealed a round, solid, movable nodule measuring 7 mm in diameter. Radiographs showed faint linear calcifications in the nodule under the right hallux proximal phalanx neck. The mass was completely excised, and pathologic observation revealed a mass composed of mature chondrocytes in a cartilaginous matrix, consistent with a chondroma. Even though this is a benign tumor, it needs to be differentiated from other tumors, including schwannoma, leiomyoma, chondrosarcoma, and others. Surgical excision is the preferred treatment.

[Thésaurus Mesh]Présentations de casMots-clés : mélanome névoïde Résumé : Nevoid melanoma (NeM) is a rare variant of malignant melanoma characterized by slight
cellular atypia, polymorphism, and incomplete maturation. It most frequently occurs on the
trunk and arms but rarely on the foot. Here, we report a subungual NeM of the right hallux. A
65-year-old man presented with severe pain of 6 months’ duration to his right great toe following self-treatment for an ingrown nail. He was evaluated and treated with debridement of
the toenail at an urgent medical center 3 months prior. However, this had not relieved his
pain. The patient also noticed discoloration of his distal great toe over the past 3 months.
Removal of part of the ingrown nail revealed a pigmented mass extending distally from the
matrix. Surgical excision of the mass was performed because of the concern for malignancy.
The diagnosis of NeM was based on histologic analysis along with enhanced diagnostic
modalities. The patient was further treated with surgical amputation of the great toe and
anti–programmed cell death-1 therapy. The patient had no relapse at 1-year follow-up.
Nevoid melanoma is a rare variant of malignant melanoma on the toes, which needs to be
differentiated from a nevus with atypia, with a variety of modalities including cellular and molecular profiling. The optimal treatment is amputationPermalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
