Syringoma: Causes and Treatments

Syringomas are benign adnexal tumors that primarily affect the eccrine sweat glands. Though often harmless, they can be a source of cosmetic concern for those affected. Check  the various aspects of syringoma, including its pathology, symptoms, causes, diagnosis, and available treatments.


What is Syringoma?

Syringomas are benign tumors typically arising from the intraepidermal portion of the eccrine sweat ducts. These small, firm, flesh-colored papules most commonly appear around the eyelids, although they can also manifest on the cheeks, axillae, and other areas. Despite their benign nature, their appearance can lead to significant cosmetic distress.


How does Syringoma Affect?

  • Syringomas can happen to anyone, but they’re most often seen in:
  • AFAB (Assigned female at birth): Refers to women and people who were assigned female at birth.
  • Individuals with Down syndrome, Marfan syndrome or diabetes.
  • People whose skin tone is on the lighter side.
  • Teenagers hitting puberty.
  • Young adults, 40–60 years of age.
  • Eruptive syringomas, one form of generalized syringoma, most commonly occur in persons with darker skin.

Syringoma Pathology Outlines

From a histological perspective, syringomas are characterized by small ducts lined by two rows of cuboidal cells. These ducts are embedded within a fibrous stroma, giving a tadpole or comma-shaped appearance. The pathology confirms their benign nature, with no malignant potential.

111Types of Syringoma

Syringomas can be classified into several types based on their presentation and associated conditions:

  • Localized Syringomas: This is the most common type, typically appearing on the eyelids and face.
  • Generalized Syringomas: These can appear on various parts of the body, including the chest, abdomen, and axillae.
  • Eruptive Syringomas: Characterized by multiple lesions appearing suddenly, often on the chest and abdomen.
  • Familial Syringomas: These occur in families, suggesting a genetic predisposition.
  • Chondroid Syringoma: Also known as mixed tumors of the skin, these are rare and contain both epithelial and mesenchymal components.

Syringoma Symptoms

Syringomas are usually asymptomatic, presenting primarily as a cosmetic concern. The lesions are typically:

  • Small (1-3 mm in diameter)
  • Flesh-colored or yellowish
  • Firm to the touch
  • Commonly located around the eyelids and upper cheeks

In rare cases, patients may experience mild itching or irritation.


Syringoma Causes

The exact etiology of syringomas is not well understood. However, several factors are believed to contribute to their development:

  • Genetic Factors: Familial cases suggest a hereditary component.
  • Hormonal Influences: These tumors are more common in women and often appear or worsen during puberty, pregnancy, or hormonal therapy.
  • Underlying Health Conditions: Syringomas have been associated with certain systemic conditions, such as Down syndrome and diabetes mellitus.

Syringomas Under Eyes

The periorbital region is the most common site for syringomas. Their occurrence here can be particularly distressing due to their visibility and impact on facial aesthetics.


Syringoma Diagnosis

Diagnosing syringomas typically involves a clinical examination by a dermatologist. The appearance of the lesions is often characteristic enough for a diagnosis. However, in uncertain cases, a skin biopsy can be performed to confirm the diagnosis histologically.

Differential Diagnosis

Several other skin conditions can resemble syringomas, making differential diagnosis crucial. These include:

Syringoma Treatment

While syringomas are benign and typically do not require treatment, those seeking removal for cosmetic reasons have several options.

Syringoma Removal Cream

There are topical treatments available that claim to reduce the appearance of syringomas. These creams often contain ingredients like retinoids or exfoliating agents to promote skin turnover and reduce lesion prominence. However, the efficacy of these treatments is variable, and they are generally not considered a first-line option.

Surgical Treatments

  • Laser Therapy: CO2 and erbium-YAG lasers can effectively vaporize syringomas, offering good cosmetic results. However, multiple sessions may be required, and there is a risk of scarring and pigmentation changes.
  • Electrosurgery: This involves using electric currents to destroy the lesions. It is effective but can also result in scarring.
  • Cryotherapy: Freezing the lesions with liquid nitrogen can be effective but may cause hypopigmentation.
  • Excision: Surgical removal of syringomas is an option, particularly for larger or more bothersome lesions. This method carries a higher risk of scarring.

Emerging Treatments

Research into new treatments for syringomas is ongoing. Techniques such as radiofrequency ablation and the use of botulinum toxin injections are being explored for their efficacy and safety.


Syringoma Prevention

Given the unclear etiology, specific preventive measures for syringomas are not well established. However, some general skin care tips may help:

  • Sun Protection: Protecting the skin from UV radiation can prevent various skin conditions.
  • Gentle Skin Care: Using non-irritating skin care products can help maintain skin health.
  • Regular Dermatological Check-ups: Early detection and treatment of skin anomalies can prevent complications.

Frequently Asked Questions

Can syringomas spread to other parts of the body?

While syringomas typically stay localized to specific areas like the face, eruptive syringomas can spread to other parts of the body, such as the chest, abdomen, and underarms. Their development in multiple areas is more common in certain individuals with genetic factors.

Are syringomas hereditary?

Yes, syringomas can be hereditary, particularly in cases where multiple family members are affected. In such cases, the condition may have a genetic component, and inheritance patterns may suggest a familial link. If syringomas are common in your family, genetic factors may play a role.

Can syringomas come back after removal?

Yes, syringomas can recur even after removal. Surgical methods such as excision, laser therapy, or electrosurgery may reduce their appearance, but they don't offer a permanent cure. Recurrence depends on individual factors, including the type and location of the syringomas.

Are syringomas painful or harmful?

Syringomas are generally not painful or harmful. They are benign, asymptomatic skin lesions and rarely cause physical discomfort. However, they can lead to cosmetic concerns, and in some cases, mild itching or irritation might occur, especially if they are irritated or inflamed.

Can lifestyle changes or diet reduce the risk of syringomas?

There’s no evidence that diet or lifestyle changes can specifically prevent syringomas. However, maintaining healthy skin through practices like using sunscreen, gentle skin care, and avoiding harsh chemicals or irritants may help reduce skin-related issues and maintain overall skin health.
