Haematology and Oncology, East Africa

Background: Bone marrow (BM) reticulin fibers can be increased in conditions such as neoplasms and autoimmune diseases (Frisch Haematol [Budap] 1982; Aharon Lupus 1997) and can lead to a clinical situation similar to osteomyelofibrosis. In healthy individuals, grade 1 and 2 reticulin have been reported in 27–70% and 4–20% of BM biopsies, respectively (Hultdin Med Onc 2007; Beckman Arch Path Int Med 1990; Bauermeister Am J Clin Path 1971). The presence of grade 1/2 reticulin was reported in the BM of up to 67% of patients with immune thrombocytopenic purpura (ITP) (Mufti J Supp Onc 2007). Theoretically, prolonged stimulation of …

Malignant Phyllodes Tumour As An Intracystic Growth With Osteosarcomatous Differentiation, Shaista Afzal Saeed, Imrana Masroor

Department of Radiology

Phyllodes tumour is an uncommon fibro epithelial tumour of breast that often presents clinically as a rapidly enlarging lump.

Geographic Variation And Environmental Conditions As Cofactors In Chlamydia Psittaci Association With Ocular Adnexal Lymphomas: A Comparison Between Italian And African Samples, Alessandro Carugi, Anna Onnis, Giuseppina Antonicelli, Benedetta Rossi, Susanna Mannucci, Anna Luzzi, Stefano Lazzi, Cristiana Cristiana Bellan, Gian Marco Tosi, Shahin Sayed, Giulia De Falco, Lorenzo Leoncini

Pathology, East Africa

A particular extra-nodal lymphoma type arises from B cells of the marginal zone (MZ) of mucosa-associated lymphoid tissue (MALT). The aetiology ofMZ lymphomas suggests that they are associated with chronic antigenic stimulation by microbial pathogens, among which Helicobacter pylori-associated gastricMALT lymphoma is the best studied. Recently, MALT lymphomas have been described in the context of chronic conjunctivitis, which can be associated with Chlamydia spp. infection. Studies from Italy showed the presence of Chlamydia psittaci in 87% of ocular adnexal lymphomas (OAL), and C. psittaci has been described in a large part of samples from Austria and Korea as well. However, …

Lymphangiosarcoma Of The Arm Presenting With Lymphedema In A Woman 16 Years After Mastectomy: A Case Report, Yasir J. Sepah, Masood Umer, Asim Qureshi, Shaista Khan

Section of Orthopaedic Surgery

Lymphangiosarcoma following breast cancer is a relatively rare entity, with around 300 cases so far reported worldwide. Affecting the long term survivors of breast cancer, lymphangiosarcoma (Stewart-Traves Syndrome) has a high mortality rate. Since lympedema following radical mastectomy or axillary clearance and radiotherapy seems to be the main predisposing factor, further research regarding modifications in the surgical technique of axillary nodes dissection as well as the development of new chemotherapeutic agents effective in lymphangiosarcoma are required.
