Abstract

Osteosarcoma, which rarely originates from the axial bones such as pelvis, presents a major challenge in limb preservation. We report a 9-year-old girl with osteosarcoma on her buttock. She underwent wide excision “modified buttockectomy” to resect the tumour with sciatic nerve involvement. One year after surgery, she was able to walk and no recurrence was found. Keywords: buttockectomy, osteosarcoma ABSTRAKOsteosarkoma, tulang aksial seperti pelvis jarang sekali ditemukan, dan menjadi tantangan besar dalam upaya penyelamatan ekstremitas. Kami laporkan satu kasus osteosarkoma pada tulang panggul-daearah bokong pada seorang anak perempuan berusia 9 tahun. Pasien menjalani eksisi luas “buttockectomy” yang dimodifikasi untuk mengangkat tumor beserta nervus ischiadikus yang terlibat. Pada pengamatan satu tahun pasca pembedahan, pasien dapat berjalan dan tidak ditemukan tanda-tanda rekurensi. Kata Kunci: buttockectomy, osteosarkoma

Abstract

BackgroundSynovial sarcoma is a rare high grade soft tissue sarcoma. Nowdays, the available therapeutic modalities has not given asatisfactory result yet. Currently, there is a promising therapeutic strategy through immunotherapy targeting NY-ESO-1 which isexpressed on tumor. The aim of this study was comparing NY-ESO-1 immunoexpression between synovial sarcoma and itshistologic mimics i.e. malignant peripheral nerve sheath tumor (MPNST) and dermatofibrosarcoma protuberans (DFSP)MethodsA cross sectional study was done in 28 cases of synovial sarcoma, 10 cases of MPNST and 17 cases of DFSP from archievalmaterial in Department Anatomical Pathology, FMUI/RSCM from January 2013 to June 2019. Immunohistohemical stainning wasperformed using an antibody NY-ESO-1 and it was described positive if it was expressed in more than 50% of tumor with moderateto strong positive intensity.ResultsThere is a significant difference (p<0.001) in NY-ESO-1 immunoexpression among synovial sarcoma (18/28), MPNST (2/10) andDFSP (1/17). Furthermore, synovial sarcoma showed a significantly higher immunoexpression compared to MPNST (OR 7.2;p=0.016; power 68.7%) and DFSP (OR 28.8; p<0.001; power 98.9%).ConclusionSynovial sarcoma showed a higher expression of NY-ESO-1 thus makes it as a good candidates for immunotherapy. There aredifferences in the expression of NY-ESO-1 in synovial sarcoma against MPNST and DFSP.

Abstract

Background: To demonstrate two rare case of primary malignant melanoma of lacrimal sac. Case Illustration: Patients were both female, 38-year-old and 46-year-old, with lacrimal sac mass,bloody discharge and epiphora. The first patient was previously diagnosed with chronic dacryocystitisand treated with antibiotics and anti-inflammation for two months which resulted in worsen conditionand enlarged swelling. Computed tomography scan revealed solid mass at lacrimal sac 13 x 12 x 7.4millimeters in size with no bone destruction. Patient underwent total mass removal surgery, whichrevealed solid highly pigmented mass. The second patient also had enlarged mass within two months.Other complaints include obstructed left nose and epistaxis. Computed tomography scan revealed solidmass at left medial canthal region involving inferior orbit, nasolacrimal duct, left nose cavity, andmaxillary sinus. Incisional biopsy revealed a malignant melanoma. Patient underwent eye exenteration,maxilectomy, and radical neck dissection. Conclusion: Primary malignant melanoma of the lacrimal sac is a rare case and often mimics chronicdacryocystitis. It’s imporant to understand this disease entity to make accurate diagnosis and managementwith the help of imaging modality.

Abstract

Primary orbital malignant melanoma is an extremely rare condition to present alone without previous extension of choroidal or conjunctival involvement. We reported the first case of malignant orbital melanoma without ocular involvement in a patient with nevus of Ota. A 52-year-old man presented with left proptosis and extensive bluish black pigmentation on left side of the face classified as Tanino type II of nevus of Ota and left ocular melanocytosis from birth. CT scan imaging showed extensive orbital mass occupying most of the orbital space. Transconjunctival biopsy was performed and a very pigmented mass was discovered, confirming the histopathology result of malignant melanoma. The patient was given up to five cycles of chemotherapy regimen. On serial orbital CT Scan, 33% of the tumor mass has disappeared after completing three cycles.
