    Giant cell tumors are commonly found over the flexor tendon sheath of the hand and wrist. However, giant cell tumors in the knee joint are rare, especially in children. We report an interesting case of an 11-year-old girl who presented with a painful lump on her right knee that enlarged over time. Clinically, she had fullness over the anterolateral part of her knee. Magnetic resonance imaging revealed an encapsulated mass inferior to the patella. The tumor measured 3 x 3.5 x 1.5 cm. Histopathological findings confirmed that it was a tenosynovial giant cell tumor. Because of initial mild symptoms, there was a delay of 2 years from the initial symptoms until tumor excision. Her follow-up period was 35 months, and her health to date is excellent with no recurrence. We believe that reporting this rare case will help clinicians update their knowledge on possible causes of lumps in the knee, and avoid diagnostic delay. It could also prove to be beneficial in arriving at a diagnosis in future cases.

    Malignant peripheral nerve sheath tumour (MPNST) with perineurial differentiation is a rare variant of MPNST. The pathological features and clinical significance of this variant remain to be characterised. We reported the clinicoradiological and pathological features of a case of recurrent right arm mass related to the ulnar nerve in a 42-year-old female patient. On pathological examination, the tumour showed dual features of conventional and perineurial MPNST which was proven by positive immunostaining for S-100 and EMA. The pathological diagnosis was MPNST with perineurial differentiation. In addition, a peculiar and rare finding of intracytoplasmic eosinophilic hyaline globules (thanatosomes) within tumour cells is reported. We document a rare tumour with hybrid features between conventional and perineurial MPNSTs. Further studies are needed to establish its biological behaviour.

    Epithelioid sarcoma is a very infrequent soft tissue sarcoma involving predominantly distal extremities of adolescent and young adult. We hereby report a case of epithelioid sarcoma in a 34-year-old young adult who presented with 1-year history of a painful left upper limb associated subsequently with warm left forearm swelling and a Volkman contracture. He was treated as an inflamed soft tissue condition of the left upper limb. A computed tomography study showed presence of multiple hypodense lesions mainly in the flexor compartment of the left arm as well at the subcutaneous tissue, which measured 1 to 1.7 cm in diameter. Histological examination of the left upper limb mass showed nodular proliferation of epithelioid tumour cells and some with rhabdoid features surrounding a central zone of necrosis and was diagnosed as epithelioid sarcoma. Concurrent presence of epithelioid sarcoma and Volkman ischaemic contracture are rarely seen in clinical practice. The present case highlights the importance of the histology which can be confused with other types of sarcoma or chronic granuloma and even missed at times thereby causing diagnostic problems.

    We present an elderly patient with a squamous cell carcinoma over the subcutaneous aspect of the leg involving the tibia. En bloc resection of the tumour together with a 10 centimetre segment of the tibia was done. The resected bone was autoclaved, replaced in its original position and stabilized with bone cement and a locked nail. This allowed early ambulation with minimal cost.

    A rectus abdominis myocutaneous flap can provide a large amount of tissue for defect coverage. Rarely a flabby and redundant abdominal tissue was used as a huge extended flap. We report a case of recurrence malignant fibrous histiocytoma of the thigh which was radically resected. The resultant massive defect was success reconstructed with an extended pedicle inferiorly based rectus abdominis myocutaneous flap.

    Pseudomyogenic (epithelioid sarcoma-like) hemangioendothelioma is a rare, low grade vascular (endothelial) neoplasm typically presenting as multicentric, superficial to deep nodules in extremities with a slight tendency of affecting young adult males. We report a case of pseudomyogenic hemangioendothelioma in a 15-year-old boy presenting initially with a 1 cm right thigh painless cutaneous lump. The lump was excised with the clinical impression of a sebaceous cyst. On microscopy, a poorly circumscribed, mild to moderately atypical spindle cell lesion in fascicular and storiform patterns with strikingly myoid-like eosinophilic cytoplasm was identified. The spindle cells were highlighted by pancytokeratin AE1/AE3, CD31, and ERG with retained INI-1, while being negative for MNF116, S100, CD34, EMA, desmin, SMA, caldesmon, myogenin, MyoD1, HHV-8 and CD163. Following the first diagnostic report, a positron emission tomography-computed tomography (PET-CT) scan revealed another 4 cm ill-defined nodule accompanied by a smaller adjacent 0.7 cm ipsilateral satellite nodule within the right psoas muscle that displayed similar morphology and immunophenotype as the cutaneous lump, supporting the multicentric feature of this unique entity. It is an uncommon yet increasingly recognised neoplasm of endothelial origin possessing a misleading myoid morphology and distinctive immunophenotype worth notifying.

    A 13 year old boy presented with a huge mass on his right arm of 6 months duration. Histopathological examination revealed sheets of malignant small round blue cells with immunopositivity for LCA, CD43, CD45Ro, CD30, EMA, ALK-1 and CD99, and negativity for CD20, TdT, myogenin, myoD1, NSE, bcl-6, bcl-2 and CD10. Fluorescent In-Situ Hybridization (FISH) testing excluded the diagnosis of Ewing's sarcoma/PNET. Pathologists need to be aware of the diagnosis of a small cell variant of ALCL, as well as of the fact that CD99 expression commonly occurs in cases of ALK-positive ALCL, in order to distinguish this entity from Ewing's sarcoma/PNET.

    Granular cell tumours (GrCTs) are uncommon soft tissue tumours that are usually benign (approximately 0.5%-2.0% have been reported as malignant). They are very rarely found at the extremities. Differentiating a malignant GrCT from a benign one is important as the former is aggressive and has a poor prognosis, whereas the latter, after surgical resection, has excellent outcomes. A malignant lesion can be suspected on clinical presentation and confirmed via histopathological examination using the Fanburg-Smith criteria.

    Soft tissue tumours are a group of remarkably diverse neoplasms that frequently pose significant diagnostic challenges to general pathologists. This study aimed to compare the agreement of histopathological diagnoses between general pathologists from various referral institutes and the referred soft tissue pathologist in a tertiary centre. The common discrepancies and their causes are also presented here. A retrospective study was conducted on 243 cases of potential soft tissue tumours referred to Hospital Kuala Lumpur, Malaysia over a period of 5 years. Reports by the referring pathologists and the soft tissue pathologist were compared based on tumour classification and tumour behaviour. Overall, there was moderate agreement in soft tissue tumour diagnoses in both tumour classification (weighted κ = 0.423) and tumour behavior (weighted κ = 0.548). The highest agreement of tumour classification was seen in the adipocytic tumours (21/28 cases), Ewing sarcoma (5/7 cases) and smooth-muscle tumours (3/5 cases). The highest rates of discrepancies were the so-called fibrohistiocytic tumours (7/11 cases), vascular tumours (9/15 cases) and undifferentiated/ unclassified sarcomas (19/32 cases). Full agreement for tumour behaviour was seen in 178 cases and there were 21 cases of zero agreement. Liposarcoma, alveolar soft part sarcoma and benign fibrous histiocytoma were the most frequent benign/malignant diagnostic discrepancies. The most common causes of discrepancy were wrong morphological interpretation followed by insufficient immunohistochemical stains performed. In conclusion, review of diagnosis by a pathologist specialized in soft tissue improves the quality of diagnosis in these heterogenous and rare tumours. A good panel of immunohistochemical stains with additional molecular study is crucial in the general hospital laboratories practice.

    PURPOSE: Inflammation plays a major role in tumour development, progression and metastasis. Multiple inflammatory markers such as absolute lymphocyte count, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet-lymphocyte ratio have been discovered as prognostic markers for various malignancies. We investigate preoperative lymphocyte count and other cell count ratios and their relation to survival and prognosis of sarcoma patients after surgery.

    METHODS: A total of 142 patients from the Orthopaedics Oncology Database were included into this retrospective study. Kaplan-Meier curve and multivariate Cox proportional models were used to calculate the overall survival of patients with sarcoma who underwent radical excision surgery.

    RESULTS: High preoperative LMR is significantly associated with better overall survival and prognosis in sarcoma patients, whereas high preoperative NLR is significantly associated with shorter overall survival and poorer prognosis. Multivariate analysis shows that LMR and NLR are good predictors for overall survival at 3 and 5 years after surgery, respectively. Patients with high preoperative lymphocytes count are associated with longer overall survival, but this association is not statistically significant. Our findings suggest that preoperative NLR and LMR are good predictive markers for survival of sarcoma patients.

    CONCLUSION: LMR and NLR can be used to identify patients at risk for poor clinical outcome, so that a more aggressive course of treatment can be applied to improve outcome. These are cost-effective prognostic tools as they are calculated from routine preoperative peripheral blood counts. In conclusion, preoperative NLR and LMR are good prognostic markers for predicting the clinical outcome of patients with sarcoma.

    Dendritic fibromyxolipoma (DFML), a rare, recently described distinct benign soft tissue tumor, has many clinicopathological features reminiscent of spindle cell lipoma and solitary fibrous tumor with myxoid change. It is distinguished histologically from both entities by the presence of spindle and stellate cells with dendritic cytoplasmic prolongations, prominent myxoid stroma with abundant keloidal collagen and occasional small plexiform vascular proliferation. We describe a case of histologically confirmed DFML of the left shoulder in a 67-year-old male, in which subsequent cytogenetic analysis revealed deletion involving 13q14.3 region in all the tumor cells, typically detected in spindle cell lipoma. In the presence of many clinicopathological similarities between DFML and spindle cell lipoma including chromosomal abnormalities, we postulate that DFML is merely a rare variant of spindle cell lipoma with extensive myxoid degeneration, and may not be considered as a separate entity. The possible differential diagnosis and their distinguishing features are briefly discussed.

    BACKGROUND: Extraskeletal (soft tissue) chondromas are rare neoplasms. They are seen most frequently in the soft tissues of hands and feet. A chondroma occurring in the breast is exceedingly uncommon. We present a case of pure chondroma of the breast in a young woman in whom fine needle aspiration (FNA) cytologic features suggested a cartilaginous neoplasm.

    CASE: A 28-year-old woman presented with a mobile lump in the left breast. Mammography showed a high-density nodule without microcalcifications. A clinical diagnosis of fibroadenoma was made. A differential diagnosis was obtained on FNA. Excisional biopsy of the lump showed the histopathologic features of chondroma. There was no recurrence or appearance of new lesion during 13 months of follow-up.

    CONCLUSION: Chondroma of the breast shows FNA cytologic features of cartilaginous tumor, but specific tumor typing may not be possible. This case highlights the difficulties that may arise in FNA diagnosis of cartilaginous tumor especially when it occurs at an unusual site. Awareness of the cytologic features combined with clinical and radiologic findings should guide the cytopathologist to make correct diagnosis of this neoplasm.

    Although studies have shown that a large proportion of cancer patients use CAM, no study on CAM use amongst orthopaedic oncology patients has been published. Therefore, this study aims to determine the prevalence, characteristics and factors associated with CAM use amongst orthopaedic oncology patients.

    Musculoskeletal tumour is much less common compared to tumours of epithelial origin. Most of these tumours are benign, with only about 1% malignant in nature. A general orthopaedic surgeon may only come across a malignant primary bone or soft tissue tumour a few times in his entire medical career. The current recommendation is for these conditions to be investigated and treated in centres with musculoskeletal oncology service. Careful clinical evaluation with appropriate plain radiography can provide adequate information for definitive diagnosis and treatment for most cases, especially the benign tumours. For some other cases, further investigations will be necessary. Magnetic resonance imaging (MRI) can provide excellent details on anatomical location of a tumour and delineate vital structures that may have been distorted by the lesion. For primary malignant tumours, computerized tomography scanning is still the gold standard for evaluation of pulmonary metastasis, and bone scan can allow early detection of distant metastasis to other bones. Whole body MRI has recently been recommended for tumour staging but the potential benefit for musculoskeletal tumour is not that convincing. PET may be very helpful for follow up detection of tumour recurrence but its role in diagnosis and staging of musculoskeletal tumours is still being evaluated...

    Sporotrichosis is a mycosis caused by a saprophytic dimorphic fungus named Sporothrix schenckii. Infections occur following traumatic inoculation of fungus from plants and infected cat bites and scratches. We report a case of a farmer who presented with a solitary subcutaneous nodule initially diagnosed as a soft tissue tumour. A history of agricultural activity and feline contact should draw the clinician's attention to sporotrichosis, as the diagnosis can be easily missed in atypical cases. The diagnosis, microbiology and management of the case are discussed.
