AbstractAbstract PDF
Diffuse large B-cell lymphoma (DLBCL) is a subtype of non-Hodgkin lymphoma (NHL) and is estimated to account for approximately 30% of all NHL cases. NHL can also occur in the female genital tract and accounts for approximately 1.5% of all NHL cases. Many doctors have difficulty diagnosing or treating vulvar DLBCL because of its very low prevalence. A 55-year-old woman presented with a solid mass on the right side of the vulva. No significantly enlarged lymph nodes were observed in the inguinal region. She underwent excisional biopsy at our institution. DLBCL was diagnosed based on histological examination. According to the Hans algorithm, the lesion was diagnosed as a non-germinal center B-cell-like subtype. The patient was referred to a hematologic oncologist. The disease stage was classified as IE according to the Ann Arbor staging classification. The patient received four cycles of chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and localized radiation therapy with 36 Gy in 20 fractions. She showed complete remission and maintained this status on the latest computed tomography scan. Gynecologists should rule out lymphoma in patients presenting with a vulvar mass.

AbstractAbstract PDF
Neurolymphomatosis (NL) is defined as the involvement of the peripheral nervous system in lymphocytic invasion. It is a very rare form of lymphoma that may occur as an initial presentation or recurrence. It affects various peripheral nervous structures and can therefore mimic disc-related nerve root pathology or compressive mononeuropathy. NL often occurs in malignant B-cell non-Hodgkin lymphomas. Notwithstanding its aggressiveness or intractability, NL should be discriminated from other neurologic complications of lymphoma. Herein, we present a case of primary NL as the initial presentation of diffuse large B-cell lymphoma (DLBCL) of the sciatic nerve. The patient presented with weakness and pain in his left leg but had no obvious lesion explaining the neurologic deficit on initial lumbosacral and knee magnetic resonance imaging (MRI). NL of the left sciatic nerve at the greater sciatic foramen was diagnosed based on subsequent hip MRI, electrodiagnostic test, positron emission tomography/computed tomography, and nerve biopsy findings. Leg weakness slightly improved after chemotherapy and radiotherapy. We report a case wherein NL, a rare cause of leg weakness, manifested as the initial presentation of primary DLBCL involving the sciatic nerve at the greater sciatic foramen.

AbstractAbstract PDF
We report a rare case of metachronous lymphoma with two distinct cell lineages in a 75-year-old man. The patient complained about having nasal obstruction for 2 years and extranodal natural killer (NK)/T-cell lymphoma of the nasal type was diagnosed from a biopsy. The immunohistochemical staining for CD56 and in situ hybridization for Epstein-Barr virus (EBV)–encoded small RNA (EBER-ISH) were positive and the tumor cells were negative for CD20. After 13 months of concurrent chemoradiotherapy, the patient presented with swelling of the left testis. Positron emission tomography scan detected an abnormal uptake in the testis. A diffuse large B-cell lymphoma, not otherwise specified, was diagnosed from subsequent radical orchiectomy. The immunohistochemical staining revealed to be positive for CD20, BCL2, BCL6, and MYC and negative for CD10 and EBER-ISH.

AbstractAbstract PDF
Primary thyroid lymphoma is a relatively rare thyroid tumor and usually a non-Hodgkin type. Its most common histologic type is the diffuse large B cell lymphoma followed by mucosa-associated lymphoid tissue (MALT). It is known to be frequently associated with autoimmune thyroiditis such as Hashimoto's thyroiditis. We report three cases of thyroid lymphoma at a single institution with a review of the literature.
