Non-Hodgkin's lymphoma on the parotid gland is a relatively rare occurrence among head and neck tumors. The mass of parotid gland lymphoma cannot be distinguished from other benign masses of the parotid gland; therefore, it is important to consider lymphoma in the differential diagnosis when examining parotid swellings and masses. Parotid gland lymphoma is most likely to be B-cell, non-Hodgkin's lymphoma of one of three types, which include follicular, marginal zone, and diffuse large B-cell, although other histologic patterns have been described. We present a review of a patient with diffuse large B-cell lymphoma (DLBCL) who presented to the Department of Oral and Maxillofacial Surgery of Pusan National University Hospital (Yangsan, Korea).

Purpose: Anaplastic large cell lymphoma, has the following three characteristics of a malignant lymphoma; 1) An irregular large nucleus, called pathologic atypical cells, 2) Eosinophilic cytoplasm, 3) Immunologically positive for Ki-1. Anaplastic large cell lymphoma occurs mostly in the lymph nodes, but about 40% has been observed to occur in other tissues. Skin is the one of the main sources of origin and it is called 'primary cutaneous anaplastic large cell lymphoma'. Methods: A 69-year-old male patient with an erythematous nodule, sized $1.5{\times}1.7cm$ on his right hand dorsum was excised under local anesthesia and on biopsy was diagnosed as 'Dermatofibrosarcoma Protuberans'. Three months after the local excision and biopsy, same natured mass reoccurred in the same region, and then spontaneous regressed after three weeks. However, metastatic large mass of $4.0{\times}5.0cm$, of same nature was observed on the elbow. The large mass was operated with wide excision and biopsy. Results: On final diagnosis, with an immunofluorescent stain with CD30(Ki-1), 'Primary cutaneous large cell lymphoma' was made. After follow up for three years, we did not observed recurrence and metastasis. Conclusion: We have reported that we have diagnosed primary cutaneous large cell lymphoma and treated without recurrence and metastasis.

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.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has received increasing interest among plastic surgeons as a long-term complication of breast augmentation. Although the prognosis is usually good, mortality is a possible outcome. Most of the cases reported in the past two decades have been from the United States, Europe, and Australia, whereas cases of BIA-ALCL in Asia remain rare. Herein, we describe the first known case of BIA-ALCL in Thailand, in which a 32-year-old woman developed BIA-ALCL 3 years after breast augmentation using textured implants. The patient underwent bilateral removal of the implants and ipsilateral total capsulectomy. This case report-the first of its kind from Thailand-should increase awareness of BIA-ALCL among plastic surgeons in Asia. The true incidence of BIA-ALCL in Asia may be underreported.

Ki-1 lymphoma is a sort of high grade large cell lymphoma and defined on the basis of the reactivity of the tumor cells with monoclonal antibody Ki-1. On fine needle aspiration cytology, the reported case is rare and the differential diagnosis is not easy, especially from undifferentiated carcinoma and Hodgkin's lymphoma. We experienced a case of fine needle aspiration cytology of Ki-1 positive large cell lymphoma in a 61-year old male patient. Fine needle aspiration cytology from the cervical lymph node disclosed hypercellular smears with large single cells on polymorphous lymphoid background. The tumor cells had abundant dense cytoplasm and large nuclei with Irregular profiles. Although most cells were mononuclear binucleated and multilobed/multinucleated cells were also seen Immunohistochemistry was done and revealed strong positive staining for Ki-1 antigen.

Anaplastic large cell lymphoma(ALCL) is an uncommon type of non-Hodgkin's lymphoma(NHL) populated with anaplastic, often bizarre cells that express CD30 (Ki-1) antigen. The unusual histologic and cytologic features may cause confusion with other neoplasms, such as poorly differentiated carcinoma, melanoma, Hodgkin's disease, or true histiocytic lymphoma. Although the cytologic features of ALCL have been well described, there are few reports about cytologic findings of the sarcomatold variant of ALCL. We experienced a case of fine needle aspiration(FNA) cytologic findings of ALCL which mimicks malignant fibrous histiocytoma. FNA cytology of chest wall mass in a 62-year-old female with a history of peripheral T-cell lymphoma(Lennert lymphoma) revealed a heterogeneous population of single cells and poorly cohesive cells with large, pleomorphic nuclei and spindle cells gathering around vascular structures within an inflammatory background. Additional features of the neoplastic cells were eccentric, multilobated nuclei with occasional 'wreath-like' configuration; abundant cytoplasm with vacuolization; and prominent nucleoli. The cytologic features suggested sarcoma, especially malignant fibrous histiocytoma. The diagnosis was made retrospectively with an aid of immunocytochemical staining.

This case report that the therapeutic effects of traditional Korean medicine(TKM) treatment on the tumor response in a diffuse large B-cell lymphoma(DLBL) patient. A patient was treated by acupuncture, pharmacopuncture, moxibustion, cupping and herbal medicine once a week at least for 12 months. we evaluated the grade of chief complaints and performed blood tests and sonography, abdominal CT periodically. After 1 month administration with TKM treatment, the symptoms of the patient vanished obviously. the size of inguinal lymphoma decreased gradually through 3 months. then from 3 to 10 months, the size of inguinal lymphoma remained as it is. TKM treatment was maintained continuously. in the abdomino-pelvic CT performed after 12 months, the patient didn't complain any symptom and the size of inguinal lymphoma decreased a little again. This case study supports that TKM treatments may have a efficacy in treating diffuse large B-cell lymphoma(DLBL) patients.

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is rare among skin malignancies. C-ALCL usually manifests as reddish or violet nodules. Surgical excision or radiation therapy is generally considered as first-line therapy, but a clinically aggressive disease may require multiagent chemotherapy. Establishing a proper diagnosis of C-ALCL is challenging but should be made to avoid inappropriate treatment and its consequences. The authors report a case of medically resolved C-ALCL in an 81-year-old man presented with well-defined nodular lesions on the forehead.

Non-Hodgkin's lymphomas are a group of highly diverse malignancies and have a strong tendency to affect organs and tissues that do not ordinarily contain lymphoid cells. Primary extra nodal lymphoma of the hard palate is rare. Here, we present a case of diffuse large B cell lymphoma in a 60-year-old male patient that manifested as slightly painful ulcerated growth on the edentulous right maxillary alveolar ridge extending onto the palate, closely resembling carcinoma of the alveolar ridge. Computed tomography images showed the involvement of the maxillary sinus and right nasal cavity, along with destruction of hard palate, superiorly extending into the orbit. This case report highlights the importance of imaging to evaluate the exact extent of such large malignant lesions, which is essential for treatment planning.

Primary spinal cord lymphomas are rare, and are either extra-/intradural masses with leptomeningeal infiltration or intramedullary in nature. The authors present a patient with a diffuse large B-cell lymphoma involving the sacral nerve root, extension to extradural space, and the cranial nerve.
