Primary Retroperitoneal Melanoma Presented in a Rare Extracutaneous Site for Malignant Melanoma

Malignant melanoma, as the name implies, is a malignant tumor of melanocytes, found in the skin, eyes, meningeal lining and the mucosal epithelium of the aero-digestive and genitourinary tracts. Malignant melanoma is typically skin malignancy, which rarely presents at extracutaneous site. Here we present a rare case of primary retroperitoneal melanoma and review the findings in comparison with other cases described in literature

Cutaneous presentation of Double Hit Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL), representing approximately 25% of diagnosed NHL. DLBCL is heterogeneous disease both clinically and genetically. The 3 most common chromosomal translocations in DLBCL involve the oncogenes BCL2, BCL6, and MYC. Double hit (DH) DLBCL is an aggressive form in which MYC rearrangement is associated with either BCL2 or BCL6 rearrangement. Patients typically present with a rapidly growing mass, often with B symptoms. Extranodal disease is often present. Though there is a paucity of prospective trials in this subtype, double hit lymphoma (DHL) has been linked to very poor outcomes when patients are treated with standard R-CHOP. There is, therefore, a lack of consensus regarding the standard treatment for DHL. Several retrospective analyses have been conducted to help guide treatment of this disease. These suggest that DA EPOCH-R may be the most promising regimen and that achievement of complete resolution predicts better long-term outcomes

Leukemia cutis in a patient with chronic lymphocytic leukemia presenting as bilateral helical nodules

Chronic lymphocytic leukemia, the most common adult leukemia worldwide, is considered an indolent but incurable non-Hodgkin lymphoma. Leukemia cutis is an uncommon manifestation of chronic lymphocytic leukemia. We present a case of an adult patient who presented with skin lesion of bilateral ears, which led to the diagnosis of chronic lymphocytic leukemia. We also reviewed the cases of auricular involvement in chronic lymphocytic leukemia patients reported in the literature. Local treatment is indicated in case of leukemia cutis; however, systemic treatment is recommended when there are systemic signs and symptoms. Better awareness of disease evolution and prompt diagnosis of this leukemia cutis of chronic lymphocytic leukemia will improve the effectiveness and outcome of its management

Relapsed Acinic Cell Carcinoma of the Parotid Gland With Diffuse Distant Metastasis

Acinic cell carcinoma (ACC) is an uncommon salivary gland neoplasm that generally displays an indolent growth pattern. Most cases arise in the major glands, particularly the parotid. However, it can arise from minor salivary glands in the oral cavity and aero-digestive tract. Although ACC is generally a low-grade malignant tumor, poorly differentiated and high-grade transformed variants exhibit a propensity for late recurrence and metastasis. There are no adequate clinical trials that define the optimal approach to patients with metastatic salivary gland tumors due to its rarity. Systemic therapy is reserved for cases where local therapy, such as radiation or metastasectomy, is not appropriate. Nevertheless, there is insufficient data in the literature regarding the chemotherapy of choice for metastatic ACC. In this article, we report a case of metastatic ACC of the right parotid gland that progressed on carboplatin and paclitaxel after partial response followed by doxorubicin and is currently on checkpoint inhibitor treatment
