An external hemorrhoid is a vascular dilation located under the skin of the anal margin, just outside the anus. Unlike internal hemorrhoids that line the anal canal and remain invisible without an anoscope, external forms present as a palpable swelling, sometimes visible to the naked eye. Understanding what medical photos of this condition show helps to better distinguish a benign situation from a sign that warrants a prompt consultation.
Skin type and color: what classic photos do not show
The vast majority of medical images available online illustrate external hemorrhoids on light skin. In these images, the swelling takes on a typical bluish or purplish appearance, indicating a subcutaneous blood clot.

On darker skin, this characteristic coloration is much less visible. The external hemorrhoid then appears more as a painful bump without obvious blue coloration. The relief and tension of the skin become the main indicators, more so than the color.
This underrepresentation of darker skin types in medical image banks has been documented in dermatology for several years. To correctly identify an external hemorrhoid, it is therefore necessary to cross-reference several visual criteria (shape, location, sensitivity to touch) rather than relying solely on the purplish hue described in most consumer information sheets. Consulting images of external hemorrhoids on Doctinews helps to compare different clinical presentations beyond just the light skin type.

Anatomy of the anal margin: reading a photo of an external hemorrhoid
Hemorrhoids are not an anomaly. They are normal vascular structures, present from birth in everyone. The SNFCP describes them as blood lakes associated with small arterial and venous vessels, organized into three to four bundles shaped like clusters of grapes attached to the wall of the anus.
Internal and external hemorrhoids in the same image
Anatomical cross-sectional diagrams show the distinction between the two types. Internal hemorrhoids line the anal canal, above the pectinate line, covered with mucosa. External hemorrhoids are located below, under the skin of the anal margin.
In a clinical photo taken from the outside, only the external shape is directly visible. It appears as a localized swelling, firm to the touch, located at the immediate edge of the anal opening. If the image shows a mass that seems to protrude from the anal canal, it is more likely to be an internal hemorrhoidal prolapse, a different mechanism.
Hemorrhoidal thrombosis: the most sought-after image
External hemorrhoidal thrombosis corresponds to the formation of a blood clot in the subcutaneous venous plexus. This is the situation that generates the most visual searches because it causes intense pain and sudden swelling.
In photos, thrombosis is recognized by several combined indicators:
- A single, rounded or oval swelling, tense under the skin, located on the immediate perimeter of the anus
- A bluish to purplish coloration (on light skin) related to the presence of the clot beneath the skin surface
- A smooth and shiny appearance of the skin in the area, indicating edema and tension in the tissues
- The absence of spontaneous bleeding in most cases (unlike internal hemorrhoids that bleed during defecation)
The associated pain is typically maximal in the first 48 to 72 hours, then gradually decreases. If a photo shows an anal lesion that is bleeding profusely or has an ulcerated crater, simple hemorrhoidal thrombosis is probably not the correct diagnosis.
Visual confusion: external hemorrhoid or other anal pathology
The main risk associated with self-diagnosis by photo is confusion with other lesions of the anal margin. Several pathologies visually resemble an external hemorrhoid without being one.
An anal abscess also presents as a painful bump, but it is often accompanied by diffuse redness, local warmth, and sometimes fever. In a photo, the abscess appears more inflammatory, with red and tense skin over a larger area than the well-defined swelling of a thrombosis.
Condylomas (anal warts) form multiple, irregular, cauliflower-like growths, which are distinctly different from the single, smooth bump of an external hemorrhoid. Tags, on the other hand, are residual skin folds after a previous thrombosis. They are neither painful nor colored, and they are a common trap in photos: they resemble a hemorrhoid but are no longer one in the active sense of the term.
Rarer lesions (anal cancer, perianal Paget’s disease) can also mimic a hemorrhoid in its early stage. Any anal lesion that persists beyond a few weeks, changes appearance, ulcerates, or is accompanied by recurrent bleeding warrants a medical examination with anoscopy.
Visual triage in teleconsultation: photographing an external hemorrhoid
Since the Covid-19 pandemic, telemedicine protocols increasingly incorporate the sending of anonymized photographs of the anal margin. This guided visual triage allows the doctor to differentiate remotely between hemorrhoidal thrombosis, an anal fissure, an abscess, or condylomas.
For a photo to be usable by a healthcare provider, a few technical principles matter:
- Direct and neutral lighting (white light), without shadows cast on the area
- A perpendicular angle to the anal margin, with a slight separation of the buttocks to expose the lesion
- Blurring or framing that excludes any identifying elements (face, recognizable tattoo) to preserve privacy
A clear and well-lit photo speeds up remote diagnosis and sometimes avoids unnecessary travel. The doctor may refer to a physical consultation if the image suggests a pathology requiring further examination.
Photos found online remain useful for orientation, but they do not replace the evaluation of a professional. A typical external hemorrhoid, even visually impressive, most often resolves spontaneously within one to two weeks. Examination by a doctor or gastroenterologist becomes necessary when pain does not decrease after a few days, when episodes recur, or when the visual appearance does not match the classic descriptions of hemorrhoidal thrombosis.
