Chondroid syringoma of an upper eyelid tumor: Unusual case report

We present the case report of a 58?year?old man with recurrent chondroid syringoma, which was histopathologically confirmed, who underwent exenteration surgery of the right eye. Furthermore, the patient was receiving postoperative radiation therapy, and presently there is no local and/or distant evidence of disease in the patient

Malignant chondroid syringoma: An unusual scalp tumor

Chondroid syringomas are similar to mixed parotid tumors and present in both benign and malignant forms. Malignant chondroid syringoma (MCS) is a rare skin tumor that has a predilection for extremities, particularly in young women. It is even rarer to present as a scalp tumor with very few reported cases in the literature. We present a middle-aged woman, with a history of increasing fatigability of her right arm for the past 3 months who, on examination, was found to have scalp swelling and matted right posterior triangle lymph nodes. The working diagnosis on her was a large sebaceous cyst with secondary in the neck from an occult primary/non-Hodgkin抯 lymphoma. Preliminary fine-needle aspiration was inconclusive. Imaging followed by wide excision of the tumor and the nearby occipital node was done. The final histopathological diagnosis was MCS with secondary in the lymph node. These tumors are aggressive and metastasize early. Radical surgery is the only hope of cure as adjuvant treatment is yet to be standardized

A unique case of eyelid metastasis from chondroid chordoma

A unique case of eyelid metastasis from nasopharyngeal chondroid chordoma in a 63-year-old woman was reported. Chordomas are rare tumors of the bone deriving from remnants of the embryonic notochord. Histologically, the tumor showed lobulated structure and concludes two types of cells: liquid drop cell and small round/cubic cell. Immunohistochemically, AE1/AE3, epithelial membrane antigene (EMA), and S100 showed a uniform and strong positivity. It has a great capacity for recurrence and malignant transformation, despite their slow-growing nature. The most common sites of metastases are liver, lungs, and bones. The eyelid metastasis from chordoma is an extremely rare finding, which may suggest a poor prognosis for the patient. Its significant clinicopathological characteristic could prompt us to take it into consideration when assessing the patient's prognosis.

Chondroid metaplasia of paraspinal connective tissue in the degenerative spine / 대한해부학회지

A 51-year-old male was routinely biopsied during a paraspinal muscle study. The biopsy sample was taken from the right erector spinae muscle at the fourth lumbar vertebra. The patient had no history of (diagnosed) major back trauma. The obtained sample was histologically analyzed (hematoxylin and eosin, safranin O), and complementary magnetic resonance imaging was performed. The biopsied sample contained chondroid tissue. Based on its location, the biopsy sample was appointed as chondroid metaplasia. Although chondroid metaplasia is not uncommon in humans, this is the first report of chondroid metaplasia within the paraspinal connective tissue. We propose a novel mechanism to explain the paraspinal chrondrogenic changes, related to spinal degeneration.

A rare case of hyaline cell-rich atypical chondroid syringoma with divergent differentiation

Chondroid syringoma (CS) also known as mixed tumor of the skin, is a rare benign adnexal tumor accounting for < 0.098%. Epithelial cells arranged in cords and tubules set in myxoid or chondroid stroma. Differentiation such as osteoid, sebaceous or mature adipocytes can be seen rarely. Hyaline cell rich is a rare variant of CS composed of cells with eosinophilic hyaline cytoplasm and plasmacytoid features. CS can have benign, atypical and malignant variants. The term atypical mixed tumor is recommended for those tumors which have histological features of malignancy such as infiltrative margin, satellite tumor nodules and tumor necrosis but without proven metastasis. Very few case reports of hyaline cellrich benign CS have been reported in the past, but to the best of our knowledge, possibly it is the first case of atypical hyaline cellrich CS of the little finger in a 65 year-old female showing divergent differentiation.

Siringoma Condroide. Presentación de un caso / Chondroid syringoma. Case presentation

Introducción: El Siringoma Condroide o tumor mixto es una neoplasia habitualmente benigna que constituye 0,01 por ciento de los tumores primarios de la piel. Es una entidad análoga al tumor mixto (Adenoma Pleomorfo) de glándulas salivales. El diagnóstico es exclusivamente histopatológico. Objetivo: Presentar una paciente con un diagnóstico poco común de Siringoma Condroide benigno, donde se destaca como diagnóstico diferencial entre los tumores de la piel en cabeza y cuello. Presentación de caso: Presentamos el caso de una paciente femenina, de 45 años de edad, quien acude a consulta por presentar un nódulo subcutáneo en la región geniana derecha, que apareció como un pequeño aumento de volumen debajo de la piel, que fue creciendo gradualmente, asintomático, redondeado, bien delimitado, móvil, de consistencia entre suave y firme, de varios meses de evolución, como única lesión. Clínicamente se interpretó como un quiste epidérmico. Su diagnóstico anatomopatológico fue el de Siringoma Condroide benigno o Tumor mixto de la piel. Conclusiones: Resulta un caso interesante debido a la baja frecuencia de presentación de esta lesión. Es importante tener presente esta entidad en el diagnóstico diferencial de los tumores de la piel en cabeza y cuello. A pesar de ser un tumor benigno es necesario el seguimiento del paciente, pues, aunque es muy raro, se han descrito casos con un comportamiento maligno(AU)

Introduction: Chondroid syringoma or mixed tumour is usually a benign neoplasia, constituting 0.01 percent of primary tumours of the skin. This is analogous to mixed tumour (Pleomorphic adenoma) of salivary gland. The diagnosis is only histopathologically. Objective: To present a patient with a diagnosis not very common of chondroid syringoma, where it is highlighted as differential diagnosis among the head and neck skin tumours. Case presentation: Is presented a case of a female patient; 45 years old, that arrived to the consulting room showing a subcutaneous nodule on the right genial region, it appeared as an asymptomatic slow-growing small mass, rounded, well bounded, mobile of soft and firm consistence, of several months of evolution, as a single lesion. The diagnosis was a chondroid syringoma or skin mixed tumour. Conclusions: It is an interesting case because it has a low frequency. It is important bear in mind this entity in the differential diagnosis of head and neck skin tumours. Despite being a benign tumour it is necessary to monitor patients, because even though it is uncommon, some cases have been reported with a malignant behaviour(AU)

Siringoma condroide en el labio superior: reporte de un caso / Chondroid syringoma of the upper lip: report of a case

Paciente masculino de 81 años de edad que acudió a consulta con un cirujano dentista por presentar una lesión nodular, asintomática, firme y móvil en el labio superior del lado derecho. El sujeto refi rió tener la lesión desde la infancia, pero notó crecimiento lento en el último año. El diagnóstico clínico indicaba un adenoma pleomorfo, por lo que el individuo se sometió a biopsia escisional bajo anestesia local. El espécimen se envió a estudio histopatológico. La evolución del paciente fue satisfactoria, sin reincidencia de la lesión. El examen microscópico reveló la presencia de una neoplasia bien delimitada constituida pormúltiples estructuras ductales pequeñas en la dermis. Estos ductos se encontraban revestidos por dos hileras de células epiteliales planas y contenían cantidades variables de material amorfo en la luz. El estroma presentaba diferenciación condroide.

An 81-year-old male patient consulted a dental surgeon due to his presenting a fi rm, mobile, asymptomatic nodular lesion on the upper lip. The patient stated that he had had the mass since childhood but that it had grown slowly over the course of the previous year. The clinical diagnosis was pleomorphic adenoma, for which reason the patient underwent an excisional biopsy under local anesthesia. The specimen was sent for histopathological examination. The patient’s progress was satisfactory and there was no recurrence of the lesion. Micro-scopic examination revealed the presence of a well-defi ned neoplasm consisting of multiple small ductal structures located in the dermis. These ducts were lined with two rows of fl attened epithelial cells and contained varying amounts of amorphous material in the lumen. The stroma exhibited chondroid differentiation.

Rare lesions of the breast Fibrocystic disease with chondroid metaplasia, giant lipoma and fibroadenoma with atypical ductal hyperplasia.

This paper focused on 3 rare lesions of breast - an exceedingly rare case of fibrocystic disease of breast with predominantly chondroid metaplasia. Giant lipoma of breast which is infrequently observed because of rarity in size and location, with only very few case reports available in literature and fibroadenoma with atypical ductal hyperplasia(ADH) of breast which is an unusual finding in the adolescent or young adult female.

Diagnostic Dilemma in Metaplastic Chondroid Breast Carcinoma

Metaplastic breast cancer is a rare form of primary breast cancer. It contains a mixture of adenocarcinoma with metaplastic elements. It is important to differentiate with primary sarcoma of the breast which carries different treatment strategies and prognosis. A 55-year-old lady previously diagnosed to have a left breast cancer in the year 2000 and carcinoma of the endometrium in 2009, presented with a right breast lump. A trucut biopsy reported as an infiltrating ductal carcinoma with background of chondromyxoid and cartilagenous matrix, most probably metaplastic carcinoma. A wide local excision with sentinel lymph node biopsy was performed, and the final histology was consistent with metaplastic chondroid carcinoma of the breast with no evidence of metastsis. The surgery was followed by adjuvant radiotherapy and currently free from any recurrence. The diagnostic dilemma on this very rare condition is reviewed.

Chondroid Syringoma: Clinical, Pathological, and Immunohistochemical Study of 23 Cases / 대한피부과학회지

BACKGROUND: Chondroid syringoma is a rare benign tumor composed of epithelial and stromal elements. Studies of chondroid syringoma are lacking in Korea and controversy still exists regarding the stromal cell origins. OBJECTIVE: To investigate the clinicopathological and immunohistochemical characteristics of chondroid syringoma in Korea. METHODS: We included 23 patients who were diagnosed with chondroid syringoma. RESULTS: There was a predilection for males (M : F=2.3 : 1), and the mean patient age was 50.4+/-15.4 years (range 22~78 years), peaking in the forties. Of the 23 cases, 22 (95.7%) had it on the head and neck. There were 21 apocrine type cases and 2 eccrine type cases. Apocrine type cases showed decapitation secretion as well as follicular and sebaceous differentiations. Myxohyaline matrix was present in all cases, and in some cases, chondroid, lipomatous, and osseous metaplasias were also observed. In apocrine type cases, inner cell layers displaying tubuloglandular structures expressed cytokeratin, carcino-embryonic antigen, and epithelial membrane antigen, while outer cell layers expressed vimentin, S-100 protein, neuron-specific enolase, and smooth muscle actin. Stromal cell immunophenotypes were similar to those of the outer layer. CONCLUSION: Chondroid syringoma was most commonly observed on the head and neck in middle-aged males. The apocrine type was far more common than the eccrine type and showed various differentiating characteristics. The matrix may contain myxohyaline stroma with alterations, including chondroid, lipomatous, and osseous metaplasias. Our immunohistochemical study suggests that myoepithelial cells play an important role in the histogenesis of chondroid syringoma and matrix production.

Siringoma condróide: relato de caso / Chondroid Syringoma: Case Report

O siringoma condróide é um tumor misto cutâneo, benigno e raro, com prevalência de aproximadamente 0,01% dos tumores de pele. Oitenta por cento dos siringomas condróides são encontrados em idosos, sendo que a proporção é de duas mulheres para cada homem. Frequentemente encontrado na região da cabeça e pescoço principalmente no couro cabeludo, face e nariz. Lesões no tronco e extremidades são extremamente raras. As lesões possuem entre 0,5 e 3 cm e são firmes e aderentes à pele, mas distinguível das demais estruturas. Neste artigo se relata um caso de uma lesão na região do lábio superior... (AU)

Chondroid syringoma is a rare benign skin mixed tumor, with a prevalence of approximately 0,01% of skin tumors. Eighty percent of chondroig syringoma are found in the elderly, and the ratio is two women for every man. Often found in the head and neck, especially on the scalp, face and nose. Typical clinical presentation of these tumours is a slow-growing, painless, firm, nonulcerated cutaneous or intracutaneous nodule (0.5-3 cm in size). This article reports a case of a lesion in the left upper lip area... 9AU)

Isolated eccentric lingual diphtheria: A relevance.

Chondroid lipoma is an unusual, unique benign lipomatous tumor. We present a case of chondroid lipoma of right thigh in 46-year- old female to highlight the distinct morphological simily, it is important to distinguish it from extraskeletal chondrosarcoma and myxoid liposarcoma. The review of the literature has been discussed.

Primary Pleomorphic Adenoma of External Auditory Canal.

Primary pleomorhic adenoma (Chondroid syringoma) arising from the external auditory canal is very rare and because of the unremarkable clinical presentation, the diagnosis is often made after microscopic examination. We reviewed the worldwide literature and found that only forty one cases have been previously reported. In this report, we describe one such unusual case. The treatment of choice is wide local excision without esthetic or functional disruption of surrounding structures, followed by careful long-term post-operative observation of the clinical course.

Intraoral chondroid lipoma with ossification – An unusual case.

Although adipocytic tumours are the most common mesenchymal tumours, chondroid variant is an extremely rare entity. Though proximal extremities, limb girdles and head, neck are common sites of occurrence, rarely cases of this unique entity have been reported in oral cavity. Chondroid lipoma due to its complex histology comprised of lipoblast like cells in myxoid and chondroid background, is aptly termed as pseudosarcomatous tumour. Importance of the knowledge of this distinct entity cannot be overestimated since it mimics soft tissue sarcoma. We report one such case of intra oral chondroid lipoma with ossification in young female.

Biopsy (PUNCH) reports moderately differentiated carcinoma infiltration. S urgical excision is decided. Discussion: Malignant chondroid syringoma is a rare tumor, but can metastasize, with prolonged survival times. It prefers limbs and trunk. Its prognosisis good when the removal is complete, but anyway it is necessary to follow up patients.

A Case of Chondroid Syringoma Involving the Eyelid Margin

PURPOSE: To report a case of chondroid syringoma that involved the eyelid margin, was accompanied by cilia loss, and required differential diagnosis with other malignant eyelid masses. CASE SUMMARY: A 46-year-old woman presented with a recurrent mass in the right lower eyelid margin, which was observed 10 years earlier, where incision and curettage had already been performed twice. The mass was neither tender nor ulcerated, was brighter in color than the neighboring skin, and had a smooth surface with cilia loss. The pathologic findings obtained from an incisional biopsy were compatible with a dermoid cyst. Full-thickness excision of the eyelid mass and direct closure were subsequently performed. The pathologic diagnosis after excisional biopsy was chondroid syringoma because cystic structures in the chondroid stroma were observed.

Recurrent posterior fossa anaplastic ependymoma with prominent chondroid metaplasia: A case report and review of literature.

We report an unusual case of a recurrent fourth ventricular anaplastic ependymoma with prominent chondroid metaplasia in a 16-year-old male. On initial presentation, the patient had a WHO Grade II tumor. However, at recurrence 1 year later, the tumor progressed to WHO Grade III tumor with more cellularity, necrosis and brisk mitotic activity. Chondroid metaplasia was present in both the initial and recurrent tumors.

Unusual nodular lesion of the tongue: clinical report of chondroid metaplasia / Lesão incomum de língua: relato clínico de metaplasia condoide

OBJETIVOS: Revisar os conceitos de metaplasia condroide e relatar um caso incomum desta rara condição que se apresentou como uma massa nodular na borda lateral da língua em um paciente adolescente. DISCUSSÃO E CONCLUSÃO: Metaplasia é a conversão, na vida pós-natal, de um tipo de célula para outra. Pode ser causada por algum estímulo anormal. A origem de cartilagem em tecidos moles bucais é desconhecida, mas várias hipóteses foram postuladas. Embora a etiopatogênese seja incerta, sugeriu-se que a metaplasia condroide ocorre como uma reação defensiva e originada de células mesenquimais miltipotentes. A metaplasia condroide é uma alteração benigna que ocorre como resposta à irritação crônica física ou química. A diferenciação entre coristoma cartilaginoso e metaplasia condroide pode ser difícil e, muitas vezes, uma questão de conceito. Considerando os achados do presente caso, a condição foi diagnosticada como metaplasia condroide de língua.

OBJECTIVES: To review the concepts of chondroid metaplasia and to report an unusual case of this rare condition, presenting as a nodular soft tissue mass in the lateral border of the tongue in an adolescent. DISCUSSION AND CONCLUSION: Metaplasia means the conversion, in postnatal life, of one cell type to another. It could be caused by some abnormal stimuli. The origin of cartilage in the oral soft tissues is unknown but several hypotheses have been postulated. Although the etiopathogenesis is unclear, it has been suggested that chondroid metaplasia may occur as a defensive reaction and it is originated from multipotential mesenchymal cells. Chondroid metaplasia is a benign change that occurs as a response to chronic physical or chemical irritation. The differentiation between cartilaginous choristoma and chondroid metaplasia could be very difficult and sometimes a matter of concept. Considering the findings of the current case, the lesion was diagnosed as chondroid metaplasia of the tongue.

A Case Report of Chondroid Syringoma of Philtrum

PURPOSE: Chondroid syringoma is a rare mixed tumor of the skin that was first described by Hirsch and Helwig (1961). Characteristically, it is composed of the proliferation of epithelial cells in a myxoid and chondroid matrix. Most lesions occur on the head and neck region, and their size may range from 0.5~3 cm. Since a chondroid syringoma presents similar characteristics to other masses on the head and neck region, it is significantly important to distinguish with other masses by a surgical biopsy. METHODS: A 51-year old woman presented with a painless nodular mass (0.5 x 0.5 x 0.5 cm) on the philtrum, which appeared during the previous year. The mass was treated with a laser without a surgical biopsy. However, the size of the mass showed no changes. Surgical excision under local anesthesia was performed and sent for histopathology. RESULTS: Gross examination showed a mass surrounded by a well developed capsule within the dermal layer. After complete excision without injury to the orbicularis oris muscle, the wound was covered with a local flap. The histology examination revealed numerous cuboid epithelial cells with tuboalveolar structures and keratinous cysts within a chondroid stroma. No recurrence or metastasis was observed at the follow-up visits. CONCLUSION: Chondroid syringoma is a rare mass on the face. An accurate diagnosis is essential for optimal treatment. This paper reports a case of a chondroid syringoma on the philtrum with a brief review of the relevant literature.
