Introdução

O que você precisa saber de cara

💬
EM LINGUAGEM SIMPLES

O lipossarcoma pleomórfico é um tipo muito raro e de crescimento rápido de câncer dos tecidos profundos, que atinge principalmente adultos. Ele costuma aparecer como um caroço ou massa nos braços ou nas pernas. A confirmação é feita por exame do tecido, pois não há exames genéticos disponíveis para identificar a condição. No momento, esta doença não possui um PCDT oficial nem medicamentos específicos com entrega cadastrada pelo SUS, sendo acompanhada nos centros médicos especializados.

Myxoid Pleomorphic Liposarcoma Imitating Recurrent Traumatic Hemopericardium.

JACC. Case reports2026 Mar 19

Primary pericardial malignancies are rare, and myxoid tumors may mimic hemorrhagic pericardial effusions on imaging, leading to diagnostic delay. A 56-year-old man presented with pleuritic chest pain and was diagnosed with acute pericarditis and a presumed traumatic hemorrhagic pericardial effusion. Despite anti-inflammatory therapy and pericardiocentesis yielding bloody, lymphocyte-predominant fluid with negative cytology, he experienced rapid clinical deterioration. Repeat imaging revealed an encasing pericardial mass causing severe left atrial compression and functional mitral stenosis. Emergent surgical exploration identified a large solid pericardial tumor. Histopathology confirmed primary myxoid pleomorphic liposarcoma. The patient underwent surgical resection followed by adjuvant chemotherapy and radiotherapy. This case highlights the myxoid tumor's masquerade as a hemorrhagic effusion, the limitations of pericardial fluid cytology for sarcoma, and the hemodynamic consequences of external cardiac compression. Persistent or recurrent bloody pericardial effusions with atypical imaging features warrant suspicion for malignancy despite negative cytology.

Surgical Strategies for Closure of Complex Posterior Trunk Defects in Myxoid Pleomorphic Liposarcoma: A Case Report and Literature Review.

Cureus2026 Feb

Myxoid pleomorphic liposarcoma (MPL) is an exceptionally rare subtype of liposarcoma characterized by an aggressive clinical course. Since its first description in 2009, fewer than a dozen cases have been reported, predominantly in pediatric populations and mediastinal locations. Reports in elderly patients and with posterior trunk involvement are exceedingly uncommon. We report the case of an 83-year-old male with a two-year history of progressive cervical-thoracic swelling, ultimately diagnosed as MPL on biopsy. Imaging revealed an 8.6 × 6.4 × 7.6 cm mass originating from the right cervico-thoracic paravertebral muscles, infiltrating trapezius, rhomboid, subscapularis, and latissimus dorsi. The patient underwent en bloc tumor excision, including paraspinal muscles and partial vertebral elements, followed by immediate reconstruction using regional rotational musculocutaneous flaps (latissimus dorsi and trapezius) performed by a combined oncologic and reconstructive surgical team. Postoperative recovery was uneventful, and the patient was discharged with preserved functional mobility and no wound complications. MPL is recognized for its high recurrence rate and poor survival. Complete surgical resection remains the cornerstone of treatment, particularly when neoadjuvant therapy is not feasible or ineffective. Reconstruction of large posterior trunk defects is technically demanding due to limited tissue elasticity and the scarcity of recipient vessels for free flaps. Regional pedicled options, including trapezius, latissimus dorsi, and paraspinous flaps, remain reliable strategies. This case emphasizes the feasibility of achieving both oncologic clearance and functional coverage in elderly patients with extensive defects. This case highlights the rarity of MPL in advanced age and posterior trunk location, underscoring the critical role of individualized reconstructive planning. Regional pedicled flaps provide safe and effective coverage, ensuring functional preservation and reduced morbidity following radical resection.

Pleomorphic liposarcoma of the breast.

Revista espanola de patologia : publicacion oficial de la Sociedad Espanola de Anatomia Patologica y de la Sociedad Espanola de Citologia2026

Primary sarcomas of the breast are exceptionally rare, accounting for fewer than 1% of malignant breast lesions. Mammary liposarcomas comprise less than 5% of all breast sarcomas, and among these, primary pleomorphic liposarcoma is particularly uncommon, with a reported frequency of less than 0.01% of malignant breast lesions. It is a highly aggressive tumour, characterised by a high recurrence rate. The characteristic microscopic findings of pleomorphic liposarcoma include atypical lipomatous cells with marked nuclear pleomorphism, as well as abundant lipoblasts, frequent mitoses, and extensive areas of necrosis. In this article, we present a case of primary pleomorphic liposarcoma of the breast.

Synchronous Retroperitoneal Pleomorphic Liposarcoma and Colonic Mucinous Adenocarcinoma.

Case reports in oncology2026

Multiple primary malignancies (MPM), defined as two or more distinct primary tumors in 1 patient, are uncommon, with synchronous presentations (diagnosed within 6 months) being rarer. The coexistence of retroperitoneal liposarcoma and a synchronous gastrointestinal malignancy, particularly colorectal adenocarcinoma, is an exceptionally rare clinical entity, posing significant diagnostic and therapeutic challenges. A 63-year-old male presented with fatigue, anorexia, and weight loss. The initial workup revealed microcytic anemia and positive fecal occult blood. While initial endoscopic biopsies were inconclusive, a contrast-enhanced CT scan identified two distinct masses: a large (20 cm) heterogeneous retroperitoneal mass suggestive of liposarcoma and a thickened right colic flexure. The patient underwent a combined en bloc surgical resection, including an extended right hemicolectomy and resection of the retroperitoneal mass with the right kidney. Histopathology confirmed two high-grade primary malignancies: a retroperitoneal pleomorphic liposarcoma (stage IIIb) and a colonic mucinous adenocarcinoma (stage pT3 pN2b). Adjuvant chemotherapy (CAPOX regimen) was initiated for high-risk colon cancer. This case highlights the necessity of a high index of suspicion for synchronous malignancies in patients with non-specific constitutional symptoms. Comprehensive cross-sectional imaging is crucial for accurate staging. Management requires a multidisciplinary approach to plan complex surgical interventions and tailor adjuvant therapy, often prioritizing the more aggressive or higher stage malignancy. This report underscores the complexity of MPM and the need for individualized patient care.

Myxoid Pleomorphic Liposarcoma: A Review and Update.

Cancer genomics &amp; proteomics2026

Myxoid pleomorphic liposarcoma (MPLPS) is an exceedingly rare and recently recognized adipocytic neoplasm that primarily occurs in children and young adults and shows a strong predilection for the mediastinum. Clinically, MPLPS demonstrates aggressive behavior and exhibits a high propensity for systemic spread and a worse overall survival. Some cases have been associated with Li-Fraumeni syndrome. Histologically, MPLPS is composed of a variable mixture of myxoid and pleomorphic liposarcoma-like components. Immunohistochemically, the tumor cells show diffuse expression of CD34 and p16 and loss of nuclear RB expression. MPLPS lacks DNA damage inducible transcript 3 (DDIT3) rearrangements and MDM2 proto-oncogene (MDM2) amplifications but shows tumor protein p53 (TP53) mutations and RB transcriptional co-repressor 1 (RB1) deletions. Moreover, recent studies have demonstrated that the most consistent molecular feature of MPLPS is genome-wide loss of heterozygosity. Surgical excision with negative margins is the mainstay of treatment for localized MPLPS. The treatment of advanced/metastatic MPLPS still poses a huge therapeutic challenge. This review provides information about the clinicoradiological features, pathogenesis, histopathology, and management currently available for MPLPS. In addition, we discuss the differential diagnosis of this novel entity.
