  • Primary thyroid lymphoma is rare and accounts for less than 5% of all thyroid malignancy. The clinical presentation includes a rapidly enlarging neck mass, associated with dysphagia, dyspnea or hoarseness. The most common histologic type is diffuse large B cell non-Hodgkin's lymphoma. Papillary thyroid carcinoma is the most common type of thyroid malignancy. Co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma is very rare. Recently, we experienced a case with co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma in a 79-year-old woman, who had tuberculous lymphadenitis presented as lateral neck mass. We present this case with a review of the literature.

  • Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently described form of T-cell non-Hodgkin lymphoma now formally recognized by the World Health Organization classification of lymphoid neoplasms. The aim of this paper is to report the first case of BIA-ALCL diagnosed in a pregnant patient. It is well known that BIA-ALCL appears as an indolent lymphoma with a good prognosis when diag-nosed at early stages and clinical guidelines for its management have been clearly published. Nevertheless, they lack a standardized approach for BIA-ALCL during pregnancy. With limited experience in our case, treatment has been safely postponed after term without affecting patient's overall prognosis and without fetal complication. The fact that the disease was diagnosed at an early stage (stage I) undoubtedly influenced the course of treatment. A multidisciplinary approach weighing the risks and benefits of treatment is of paramount importance in order to ensure the best possible outcome for both the mother and her child and clinical update guidelines should be issued.

  • When therapeutic irradiation is indicated for the orbital tumors, the greatest concern is the risk of radiation-induced cataract. Conjunctival lymphoma is one of the good examples. We would like to report the procedure of the lens shielding device(L.S.D) and the result of irradiated dose to the lens. L.S.D. consistes of two parts : load alloy to attenuate electron beam, and dental acryl which completely covers the lead alloy to avoid discomfort of cornea from contacting directly with cerrobend and side scattering by cerrobend. And for easy location and removal, side bars were made on each side. Radiation doses were meaured with TLD(TLD 3500 Hawshaw). Markus chamber in a polystyrene phantom. The phantom was irradiated with 9MeV electron beams from Clinac 2100C with $6{\times}6cm$ electron cone. The relative dose at 6mm depth where the lens is located was $4.2\%$ with TLD and $5.1\%$ with Markus chamber clinically when 2600 cGy are irradiated to the eyeball, the mapinary dose to the lens will be 109 cGy or 132 cGy, which will significently reduce the cataract.

  • The present study attempted to apply polymerase chain reaction (PCR) to develop a rapid differential diagnosis among Marek's disease, reticuloendotheliosis and avian leukosis. The primers chosen to detect Marek's disease virus (MDV) flank the 132bp tandem direct repeat of the MDV genome. The primers selected for reticuloendotheliosis virus (REV) and avian leukosis virus (ALV) are based on proviral long terminal repeats of spleen necrosis virus and Rous-associated virus-2 genomes, respectively. The specific PCR products of MDV, REV and ALV were observed with each primer and the reaction was not cross-reacted among the viruses. MDV-specific DNA was also amplified from the MDV-induced lymphoma (MDCC-MSB1) but not from the REV-induced tumor and ALV-induced lymphoma (LSCC-1104B1). In addition, proviral DNA of REV from REV-induced tumor and proviral DNA of ALV from ALV-induced lymphoma were also amplified by REV-specific and ALV-specific PCRs, respectively. Therefore these three PCR methods may be used to rapidly differentiate among MDV, REV and ALV-associated tumors in diagnosis.

  • From April 1985 to September 1989, 26 patients with stage I and II non-Hodgkin's lymphoma of unfavorable histology localized in head and neck region were treated with combined modality (combination chemotherapy plus radiotherapy) at the Department of Therapeutic Radiology in Kyungpook National University Hospital. Of the 26 patients, 23 showed complete response and 3 partial response. Between these two groups there were no statistical differences according to the variables. Three-year survival and disease-free survival rate were $62.4{\%}$ and $65.2{\%}$, respectively. Unilateral involvement of neck node (p<0.05), radiation dose over 5000 cGy (p<0.01), and 6 or more cycles chemotherapy (p=0.06) had a favorable effect on 3-year survival rate. There were 8 recurrences including 3 partial responders, 1 local failure, 1 distant failure, 1 contiguous failure, and 2 simultaneous local and distant failure. It could be suggested that combined modality treatment might be necessary for the treatment of stage I and II Non-Hodgkin's lymphoma of unfavorable histology.

  • Bleomycin-induced pulmonary toxicity usually occurs in the elderly patients (greater than 70 years old), patients with a cumulative dose above 400 units, previous chest radiotherapy, oxygen therapy, and renal failure. However, there are some reports of severe pneumonitis that developed after administering low bleomycin doses(less than 100 units). In severe bleomycin-induced pneumonitis in non-Hodgkin's lymphoma patients, the response to corticosteroid is poor and the mortality rate is very high, approximately 83%. Therefore, clinicians should have a low threshold for investigating and treating bleomycin-induced pneumonitis. Here, we report a case of severe bleomycin-induced pneumonitis as a complication of a non-Hodgkin's lymphoma treatment.

  • Curcumin, a natural compound extracted from rhizomes of curcuma Curcuma species, has been shown to possess potent anti-inflammatory, anti-tumor and anti-oxidative properties. However, the mechanism of action of the compound remains poorly understood. In this report, we have analyzed the effects of curcumin on the cell proliferation of Burkitt's lymphoma Raji cells. The results demonstrated that curcumin could effectively inhibit the growth of Raji cells in a dose- and time-dependent manner. Further studies indicated that curcumin treatment resulted in apoptosis of cells. Biochemical analysis showed that the expression of Bax, Bid and cytochrome C were up-regulated, while the expression of oncogene c-Myc was down regulated after curcumin treatment. Furthermore, poly (ADP-ribose) polymerase (PARP) cleavage was induced by the compound. Interestingly, the antiapoptotic Bcl-2 expression was not significantly changed in Raji cells after curcumin treatment. These results suggested that the mechanism of action of curcumin was to induce mitochondrial damage and therefore led to Raji cell apoptosis. We further investigated the in vivo effects of curcumin on the growth of xenograft tumors in nude mice. The results showed that curcumin could effectively inhibit tumor growth in the xenograft mouse model. The overall results showed that curcumin could suppress the growth of Burkitt's lymphoma cells in both in vitro and in vivo systems.

  • Background: Hodgkin's lymphoma (formerly, Hodgkins disease) is a potentially curable malignancy with distinctive biological behavior and specific clinical characteristics. Limited information is available from developing countries for patients with classical Hodgkin's lymphoma (cHL). Therefore we reviewed the demographical and clinico-hematological profiles along with bone marrow infiltration patterns in adult patients presenting at Liaquat National Hospital and Medical College. Materials and Methods: In this cross sectional study, 62 adult (${\geq}15years$) patients with cHL were enrolled from January 2010 to December 2014. Results: The mean age was $29.7{\pm}13.8years$ with a median of 30 years. The male to female ratio was 2:1. B symptoms were present in 72.5% of patients and lymph node enlargement in 85.4%. The frequency of bone marrow infiltration in our cHL patients was found to be 27.4%, the pattern being predominantly focal followed by diffuse. The mean hemoglobin was $9.4{\pm}1.9g/dl$ with a mean MCV of $78.1{\pm}7.9fl$, a mean total leukocyte count of $10.9{\pm}20.6{\times}10^9/l$ and a mean platelet count of $241.6{\pm}150.1{\times}10^9/l$. Conclusions: Our analysis shows that clinico-pathological features of cHL in Pakistan are comparable to published data. Peripheral lymphodenopathy associated with B symptoms is the commonest presentation. Bone marrow involvement is more common in our setup as patients usually presented at an advanced stage of disease.

  • Purpose: To retrospectively analyze dosimetric parameters of volumetric-modulated arc therapy (VMAT) and three-dimensional conformal radiotherapy (3D-CRT) delivered to extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue in the stomach (gastric MALT lymphoma) to find out advantages of VMAT and conditions for definite benefits of VMAT. Materials and Methods: Fifty patients with stage I-II gastric MALT lymphoma received VMAT (n = 14) or 3D-CRT (n = 36) between December 2005 and April 2018. Twenty-seven patients were categorized according to whether the planning target volume (PTV) overlaps kidney(s). Dosimetric parameters were analyzed by dose-volume histogram. Results: Radiation dose to the liver was definitely lower with VMAT in terms of mean dose (p = 0.026) and V15 (p = 0.008). The V15 of the left kidney was lower with VMAT (p = 0.065). For those with PTV overlapping kidney(s), the left kidney V15 was significantly lower with VMAT. Furthermore, the closer the distance between the PTV and kidneys, the less the left kidney V15 with VMAT (p = 0.037). Delineation of kidney(s) by integrating all respiratory phases had no additional benefit. Conclusions: VMAT significantly increased monitor units, reduced treatment time and radiation dose to the liver and kidneys. The benefit of VMAT was definite in reducing the left kidney V15, especially in geometrically challenging conditions of overlap or close separation between PTV and kidney(s).

  • A 7 years-old intact female dog (4.8 kg) was referred with primary complaints of enlarged surface lymph nodes, cardiac murmur, coughing and exercise intolerance. Diagnostic imaging studies found cardiomegaly with distended caudal vena cava, marked left ventricular and interventrciular septal thickening and flattening, severe aortic and pulmonic stenosis (~5 m/s), and mitral and tricuspid regurgitation (~4 m/s). Cytology for the samples obtained from submandibular lymph node and left ventricle revealed high grade malignant lymphoma. The case was diagnosed as cardiac lymphoma. The dog was treated with prednisolone (2 mg/kg, PO, q24h), lomustine (80 $mg/m^2$ PO, q3wk), diltiazem (1 mg/kg, PO, q12h) and enalalpril (0.5 mg/kg, PO, q12h). The clinical signs were improved after therapy. The dog is still on the chemotherapy and regularly checked up.
