RESUMEN
BACKGROUND: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy arising from precursor dendritic cells. It is a rare and challenging clinical presentation. For decades, there has been no treatment course for managing BPDCN and its overall prognosis is poor. METHODS AND RESULTS: We report a 27-year-old man who was admitted to the hospital due to an orbital tumor as the first symptom. Progressive enlargement of the orbital tumor was accompanied by multiple purple circular nodules on the body trunk. Pathological confirmation of BPDCN after resection of the orbital mass. Bone marrow smear and flow cytometry on examination indicate AML-M5. Performance of chemotherapy and peripheral blood autologous stem cell transplantation. CONCLUSIONS: The clinical manifestations of blastic plasmacytoid dendritic cell neoplasms are diverse. The diagnosis of BPDCN can be difficult due to overlapping morphologic, immunophenotypic, and clinical features of other hematologic AML. Relapsed and refractory BPDCN remains an elusive therapeutic challenge. The future of new targeted therapeutic drugs is expected.

INTRODUCTION: Teratoma is the most common congenital tumor, but the orbital location is rare. It is composed of tissues from ectoderm, mesoderm, and endoderm. CLINICAL PRESENTATION: Congenital orbital teratoma commonly presents as unilateral proptosis, with rapid growth, leading to exposure keratopathy. DIAGNOSIS: Prenatal ultrasound may detect the orbital mass, computed tomography (CT) scans, and magnetic resonance (MR) imaging are better in demonstrating multilocular cystic and solid mass, without bone erosion. Laboratory tests should include alfa-fetoprotein (AFP) and B-human chorionic gonadotropin (B-HCG), and histopathologically, it contains all three germ cell layers components. The management is surgical removal of the lesion, the mature teratoma has a benign behavior, and the immature has a poor prognostic. We describe a rare case of congenital orbital teratoma with intracranial extension of the lesion, in which was treated with orbital exenteration. After surgery, AFP levels decreased, the middle face displacement has improved and development milestones were appropriate.

OBJECTIVES: To assess the usefulness of ultrasonography in the diagnosis and evaluation of extraocular intra-orbital lesions in pediatric patients. METHODS: Twenty-three pediatric patients with intra-orbital lesions who underwent both ultrasound and computed tomography/magnetic resonance imaging (CT/MRI) were included. The following parameters were evaluated using ultrasound: 1) lesion detection rate (presence or absence of lesions), 2) lesion characteristics, 3) lesion location (extraconal or intraconal), and 4) the lesion longest linear dimensions, and these were compared using Fisher's exact test and Mann-Whitney U test. RESULTS: Two lesions could not be detected using ultrasound; in the other 21 cases, the lesion characteristics diagnosed by ultrasound were correct. Diagnostic accuracy of detection and characteristics assessment using ultrasound were 91.3% and 91.3%, respectively. The lesion location was not significantly different between the two groups (intraconal/extraconal in those detected using ultrasound versus those in the absence on ultrasound = 7/14 versus 0/2, P > .999); however, in two cases that were not detected on ultrasound, the lesions were located at extraconal. Lesions that were small in longest linear dimensions on CT/MRI were not detected using ultrasound (the longest linear dimensions in lesions detected using ultrasound versus that in the absence of ultrasound: 29.5 ± 8.2 [range, 13-46] versus 10 and 11 mm, P = .043). CONCLUSIONS: Ultrasonography proved to be useful for visualizing and evaluating intra-orbital lesions except for lesions that were relatively small in size. Therefore, although ultrasound could not detect lesions located behind bone and bone invasion, it could be used for diagnosing and selecting treatment strategies for intra-orbital lesions.

Ocular melanocytosis is a well-established risk factor for choroidal melanomas but, despite its reported associations in the literature, it is infrequently discussed in relation to orbital melanomas. The authors describe a teenage patient with ocular melanocytosis who presented with an asymptomatic ipsilateral right orbital mass associated with the lateral rectus muscle. An exploratory orbitotomy revealed a lesion lightly adherent to the underlying sclera. Histopathology demonstrated a markedly atypical epithelioid melanocytic proliferation, bound by a thin rim of superficial sclera, implying an origin from intrascleral melanocytes, likely within an emissary canal. Next-generation sequencing identified GNAQ and NF1 mutations. The histopathology and molecular genetics designated the lesion as having a uveal melanoma-like profile, suggesting that it may behave as a choroidal melanoma. This case underscores the importance of the association between ocular melanocytosis and orbital melanoma and provides additional evidence for primary orbital melanoma etiopathogenesis.

A case is presented of a 43-year-old male with a chronic history of progressive nasal obstruction and epiphora. MRI confirmed a heterogeneous mass involving the middle and superior turbinates with T2 hyperintense and calcified components, with extension into the inferomedial orbit. Tissue biopsy revealed a grade 2 chondrosarcoma of the conventional subtype. Endonasal wide local resection of the lesion was performed with clear margins. The patient had no functional sequelae and will undergo routine surveillance.

PURPOSE: Epidermoid cysts (EC) and dermoid cysts (DC) typically appear as well-circumscribed lesions on CT. This study aimed to clarify the radiologic and histopathologic characteristics of orbital EC and DC and to determine the correlations between them. METHODS: The medical records of 69 patients who underwent surgery for orbital DC or EC at Samsung Medical Center between January 2001 and August 2016 were retrospectively reviewed. The size and location of the cysts, rim enhancement, homogeneity of contents, presence of hemorrhagic or calcific components, radiodensity of contents, and extent of bony remodeling were evaluated using CT. Additionally, the cyst lining and contents were examined histopathologically. RESULTS: Among patients with orbital cysts, EC and DC were diagnosed in 10 (14.5%) and 59 (85.5%) patients, respectively. Further, 50.0% of EC and 79.7% of DC were located in the superotemporal quadrant of the orbit. On orbital CT, the average radiodensity of EC and DC was 18.9 ± 56.2 and -67.9 ± 63.3 HU, respectively. The cystic contents were more frequently homogeneous than heterogeneous in both EC and DC; however, the radiodensity of cysts differed significantly, which may be attributed to sebaceous gland activity. Focal bony notching, bone remodeling under pressure, and bony changes from dumbbell-shaped cysts were observed more frequently in DC than in EC. CONCLUSIONS: Radiological and histopathological features are correlated in orbital EC and DC. Therefore, orbital EC and DC can be preoperatively differentiated using CT, based on the average radiodensity and bony remodeling.

PURPOSE: To delineate specific imaging characteristics of solitary fibrous tumors, schwannomas, cavernous venous malformations, and well-circumscribed orbital lymphoma. METHODS: Patients undergoing excisional biopsy of solitary fibrous tumor, schwannomas, cavernous venous malformations, or well-circumscribed orbital lymphoma with preoperative MRIs available for review were identified at 3 academic centers in the United States and Australia. An exploratory statistical analysis was performed to identify important radiologic features, which were subsequently included in a random forest model. Histopathologic correlates were evaluated in representative cases. RESULTS: A total of 91 cases were included with a mean age of 52.9 ± 17.2 years. Nearly all solitary fibrous tumors were located in the anterior or mid orbit (87.5%) and they more commonly demonstrated intralesional heterogeneity on T2-weighted imaging (45.5%) ( p < 0.01). Compared with the other tumors, schwannomas tended to be intraconal (66.7%) and were often in the mid or posterior orbit (83.4%) ( p < 0.01). Cavernous venous malformations characteristically demonstrated progressive contrast enhancement (93.9%; p < 0.01). Most lesions in all 4 groups were hypointense on T1-weighted imaging (80%-100%; p = 0.14) and only well-circumscribed orbital lymphoma tended to also be hypointense on T2 (81.8%) ( p < 0.01). Finally, cases of lymphoma had significantly lower apparent diffusion coefficient ratios (0.9 ± 0.2) ( p < 0.001), while the other 3 groups were not significantly different from one another (cavernous venous malformations: 1.8 ± 0.4; schwannomas: 1.8 ± 0.5; and solitary fibrous tumor: 1.6 ± 0.6) ( p = 0.739). CONCLUSIONS: Key features that aid in the differentiation of these 4 tumors from one another include T2 intensity and homogeneity, early contrast-enhancement pattern, and ADC ratio.

Rhabdomyoma of the orbit is a rare tumor with very few cases reported in the literature. We herein describe a 5-year-old boy who presented to us with a deviation of his left eye. Magnetic Resonance Imaging (MRI) showed a well-defined homogeneous intraconal mass in the superomedial aspect compressing the optic nerve. An excision biopsy was performed and the diagnosis of rhabdomyoma was confirmed on histopathology and immunohistochemistry with a coincidental finding of Trichinella spiralis larvae within the excised specimen. We report this phenomenon in two rare diseases with a predilection for striated muscle occurring simultaneously in a single patient.

PURPOSE: To study the epidemiological profile of various pediatric orbital tumors and determine their clinicopathological correlation over 20 years. METHODS: A retrospective analysis of all pediatric patients with orbital tumors from the medical records between 1995 and 2015 was done. Tumors were categorized based on their cellular origin. Demographic details, clinical and histopathological diagnoses, frequency, and clinicopathological correlation were studied. RESULTS: A total of 265 pediatric patients with orbital tumors were analyzed, of which 145 (54.7%) patients were males and 120 (45.3%) were females. The mean age was 7 years (median: 6 years; range: 10 days-16 years). The distribution of lesions in each group was as follows: vasculogenic, 76 (28.7%); lipogenic and myxoid, 66 (25%); myogenic, 31 (11.7%); optic nerve and meningeal, 22 (8.3%); lymphoid and lymphoproliferative, 18 (6.8%); secondary orbital tumors, 14 (5.2%); histiocytic, 9 (3.4%); miscellaneous, 9 (3.4%), lacrimal gland, 8 (3%); mesenchymal with neural differentiation, 6 (2%); osseous, 4 (1.5%), and fibrocystic, 2 (0.8%). The most common benign and malignant pediatric orbital tumors were dermoid cysts (65, 24.5%) and rhabdomyosarcoma (31, 11.7%). A statistically significant ( P < 0.0001) clinicopathological correlation was observed in 208 (83.2%) out of 250 biopsy-proven cases. CONCLUSION: Pediatric orbital neoplasms include a broad spectrum of benign and malignant lesions. Vasculogenic tumors constitute the majority of them, followed by lipogenic and myxoid tumors. A thorough knowledge of the incidence, clinical profile, imaging features, and histopathology of specific orbital tumors aids in accurate diagnosis and their successful management.

This epidemiological study examined ocular and orbital lymphomas in the United States from 1995 to 2018, using data from the North American Association of Central Cancer Registries database of 87,543 patients with ocular and adnexal malignancies. We identified 17,878 patients (20.4%) with ocular and orbital lymphomas, with an age-standardized incidence rate (ASIR) of 2.6 persons per million (ppm). The incidence was the highest in the orbit (ASIR = 1.24), followed by the conjunctiva (ASIR = 0.57). Non-Hodgkin B-cell lymphoma was the most prevalent subtype (85.4%), particularly marginal-zone lymphoma (45.7%). Racial disparities were noted, with Asia-Pacific Islanders showing the highest incidence (orbit, 1.3 ppm). The incidence increased significantly from 1995 to 2003 (Average Percent Change, APC = 2.1%) but declined thereafter until 2018 (APC = - 0.7%). 5-year relative survival (RS) rates varied, with the highest rate for conjunctival lymphoma (100%) and the lowest for intraocular lymphoma (70.6%). Survival rates have generally improved, with an annual increase in the 5-year RS of 0.45%. This study highlights the changing epidemiological landscape, pointing to initial increases and subsequent decreases in incidence until 2003, with survival improvements likely due to advancements in treatment. These findings underscore the need for further research to investigate the root causes of these shifts and the declining incidence of ocular lymphoma.

Cavernous hemangioma, currently known as "cavernous venous malformation," is a common, benign, non-infiltrative, slowly progressive vascular malformation of the orbit presenting in adults. We report the case of a 9-year-old girl who presented with a painless palpable mass over the right upper eyelid of 7 years' duration. A computed tomography scan of the orbits revealed a heterogeneously enhancing, well-circumscribed mass in the right upper eyelid with no orbital extension. A transcutaneous excisional biopsy with histopathology disclosed cavernous venous malformation. The majority of cavernous venous malformations are intraconal and present in the fourth to fifth decade of life.

BACKGROUND: Sinonasal malignancies (SNMs) frequently present with orbital invasion. Orbital exenteration (OE) can lead to significant morbidity. Induction chemotherapy (IC) is a promising treatment alternative that may allow for orbit preserving (OP) treatments without compromising patient survival. This systematic review was conducted to synthesize the published data on SNM patients with orbital invasion who underwent IC, including tumor response, orbital outcomes, and survival. METHODS: The study protocol was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Databases Embase, Cochrane, Medline, and Scopus, from inception to July 17, 2023, were searched. RESULTS: Nineteen studies were included, encompassing 305 SNM patients with orbital invasion treated with IC. Fourteen studies reported an overall IC response rate (positive response defined as complete or partial tumor volume reduction) of 77.2%. Among included studies, OE rates after IC ranged from 0 to 40%. Three studies reported a high rate of posttreatment functional orbital preservation (89.8-96.0%). Five studies specifically reported that 62.5% (60 out of 96) of patients were downgraded from planned OE to OP treatment following IC. Three studies reported a significant overall survival (OS) improvement in IC responders versus IC nonresponders. Following IC, 5-year OS ranged from 44.2 to 55.5%. Patients with olfactory neuroblastoma demonstrated the highest IC response rate and lowest OE rate (100 and 0%, respectively) versus those with sinonasal undifferentiated carcinomas (68.4 and 0%) or squamous cell carcinomas (76.7 and 16%). CONCLUSIONS: For select patients, IC may allow for OP in locally advanced SNMs with orbital involvement.

Vascular anomalies comprise a wide spectrum of clinical manifestations related to disturbances in the blood or lymph vessels. They correspond to mainly tumors (especially hemangiomas), characterized by high mitotic activity and proliferation of the vascular endothelium, and malformations, endowed with normal mitotic activity and no hypercellularity or changes in the rate of cell turnover. However, the classifications of these lesions go beyond this dichotomy and consist various systems adapted for and by different clinical subgroups. Thus, the classifications have not reached a consensus and have historically caused confusion regarding the nomenclatures and definitions. Cavernous venous malformations of the orbit, previously called cavernous hemangiomas, are the most common benign vascular orbital lesions in adults. Herein, we have compiled and discussed the various evidences, including clinical, radiological, morphological, and molecular evidence that indicate the non-neoplastic nature of these lesions.

ABSTRACT: We report an unusual presentation of an orbital spindle cell hemangioma in a 40-year-old male, who noted sudden redness and swelling of the left eye on waking up. On examination, the patient was found to have edema of upper eyelid edema, periorbital ecchymosis, and subconjunctival hemorrhage in the left eye at presentation. On treatment with topical medications, patient had transient symptomatic relief; however, he later developed blurring of vision. When seen 10 days later, the patient's left eye showed axial proptosis. Radiological investigations revealed an intraconal soft tissue mass in the left medial rectus. Emergency orbital decompression with mass excision was done; histopathological examination of the excised mass revealed spindle cell hemangioma. Postsurgery patient had complete restoration of vision. To our knowledge, an acute presentation of an orbital hemangioma with subconjunctival hemorrhage and periorbital ecchymosis, visual loss doesn't occur commonly; hence, such presentations have to be reviewed with care.

A female, in her 60s, presented with pain and swelling of the right eye for 3 years. The radiological work-up revealed an extraconal solid-cystic orbital tumour suggestive of an epidermoid cyst. The patient underwent supraorbital craniotomy with a gross total excision of the tumour. An intraoperative diagnosis was sought, which on both squash smear and frozen section showed features of craniopharyngioma (CP), later confirmed on paraffin sections and immunohistochemistry. The orbit is a very rare site for ectopic CP, with only two cases reported in the literature. Many theories have been proposed to explain the occurrence of CP at ectopic sites. This report aims to provide insight into the different hypotheses of the pathogenesis of ectopic CP through a review of the literature.
