petechiae are tiny red, purple, or brown pinpoint spots on the skin or mucous membranes caused by small amounts of bleeding under the surface. They are usually flat (not raised) and often do not blanch (turn white) when pressed. In cosmetic and plastic surgery settings, petechiae are most often discussed as a physical finding after pressure, suction, trauma, or certain skin procedures. They can appear in both reconstructive and aesthetic care as a clue to skin or blood-vessel response.

purpura is a purple-to-red discoloration on the skin or mucosa caused by blood leaking from small vessels into surrounding tissue. It is a clinical finding (a sign), not a procedure or a product. It can appear after cosmetic and plastic surgery procedures, and it can also occur in general medical conditions. Clinicians use the term to describe and communicate a specific pattern of bleeding under the skin.

– erythema is a visible redness of the skin caused by increased blood flow in superficial vessels. – It is a clinical sign (a finding), not a diagnosis by itself. – It is commonly discussed in cosmetic dermatology and plastic surgery when assessing skin reactions to procedures. – It is also used in reconstructive settings to monitor inflammation, irritation, and healing.

telangiectasia is a visible widening of small, superficial blood vessels near the skin or mucosal surface. It often appears as fine red, pink, purple, or blue lines (“spider veins” on the face or legs). The term is used in both cosmetic care (appearance-focused treatment) and reconstructive/medical care (as a clinical sign). It describes a finding, not a single procedure.

A closed comedone is a type of acne lesion caused by a clogged hair follicle (pore) that is covered by a thin layer of skin. It often appears as a small, skin-colored or whitish bump and is commonly called a “whitehead.” It is used as a clinical term in dermatology and cosmetic skin care to describe non-inflammatory acne and texture irregularities. In plastic and cosmetic settings, it is relevant during skin assessment before and after procedures that affect the skin surface.

An open comedone is a type of acne lesion commonly called a “blackhead.” It forms when a hair follicle (pore) is plugged with keratin and sebum but remains open to the skin surface. The dark color is typically due to oxidation and light scattering at the surface, not “dirt.” It is most often discussed in cosmetic dermatology and aesthetic skin care, sometimes alongside pre- and post-procedure skin optimization.

A comedone is a clogged hair follicle (pore) filled with keratin (skin protein) and sebum (oil). It is a primary lesion of acne and is commonly called a “blackhead” or “whitehead.” The term is used most often in dermatology and cosmetic skin care, and it is also relevant in aesthetic-plastic settings where skin quality affects procedural planning and outcomes.

– urticarial means “hive-like,” describing raised, itchy welts on the skin that can come and go. – It is a clinical descriptor used in dermatology, allergy, and general medicine to characterize a rash pattern. – In cosmetic and plastic surgery settings, it commonly appears in notes about skin reactions after medications, injectables, dressings, or antiseptics. – It may be used in both cosmetic and reconstructive care because skin reactions can occur across many procedure types.

A wheal is a raised, swollen area of skin that often looks like a “welt” or hive. It is usually temporary and commonly comes with surrounding redness (a “flare”). Clinicians use the term in both medical dermatology and in cosmetic settings when evaluating skin reactions after procedures. A wheal can be a sign of urticaria (hives), allergy-related reactions, or irritation from physical triggers.

A cyst is a closed, sac-like pocket in the body that contains fluid, semi-solid material, or air. A cyst can form in the skin, under the skin, or within deeper tissues and organs. In cosmetic and plastic practice, a cyst is commonly discussed when it affects appearance, comfort, or scarring risk. cyst evaluation and treatment can be relevant in both cosmetic care (appearance-focused) and reconstructive care (function-focused).

A pustule is a small, raised skin lesion that contains visible pus. It is a descriptive clinical term used in dermatology and general medicine, not a cosmetic “procedure.” A pustule can occur on the face or body and may be inflammatory, infectious, or both. In cosmetic and plastic settings, the word helps clinicians document skin findings and recognize possible complications.

A bulla is a fluid-filled blister on the skin that is larger than a small vesicle. It is commonly described in dermatology, wound care, and surgical aftercare when the skin separates and fills with fluid. In cosmetic and plastic surgery settings, a bulla may appear as a complication of friction, adhesives, burns, or energy-based treatments. The term is also used in other fields (for example, “pulmonary bulla” on lung imaging), depending on context.

– vesicle is a small, fluid-filled blister on or just under the skin surface. – It is a descriptive clinical finding, not a cosmetic procedure or product. – Clinicians use the term in both reconstructive and cosmetic settings to document skin changes, complications, or diagnoses. – vesicle size is typically small (often described as under about 1 cm), and larger fluid-filled blisters are often called bullae.

A tumor is an abnormal growth of tissue that forms a lump or mass. A tumor can be benign (non-cancerous) or malignant (cancerous). The term tumor is used in both reconstructive and cosmetic settings because masses can affect appearance, comfort, and function. In plastic surgery, tumor often refers to a lesion that may need biopsy, removal, and reconstruction to restore form and minimize visible change.

A nodule is a small, distinct lump that can be felt or seen in tissue. It is a descriptive clinical term, not a diagnosis by itself. A nodule can occur in skin, fat, muscle, gland tissue, or deeper structures. In cosmetic and reconstructive care, the term is commonly used when evaluating lumps after injectables, implants, fat transfer, or surgery.

A plaque is a broad, flat or slightly raised area on the skin or mucosa that is usually larger than a papule. It is a descriptive clinical term, not a single diagnosis. plaque is used in both cosmetic and reconstructive settings because it can affect appearance, texture, and sometimes function. Examples include inflammatory plaques (like psoriasis), keratotic plaques (thickened surface), and fibrotic plaques (scar-like thickening).

A papule is a small, solid, raised bump on the skin. It is usually less than about 1 centimeter in diameter. The term papule is used in dermatology and aesthetic medicine to describe what a lesion looks and feels like. It is relevant in both cosmetic and reconstructive settings because skin findings can affect diagnosis, timing, and treatment planning.

A patch is a material applied on the surface of the body or placed inside the body to cover, reinforce, or replace tissue. In cosmetic and plastic surgery, patch may refer to an implantable surgical patch (biologic or synthetic) or a topical dressing-style patch. It is used in both reconstructive and cosmetic settings to support healing, contour, strength, or scar management. The exact meaning depends on the clinical goal and the material and manufacturer.

A macule is a flat, circumscribed area of skin that differs in color from the surrounding skin. It is not raised, not fluid-filled, and not felt as a bump when you run a finger over it. The term is used in clinical dermatology and in cosmetic consultations to describe surface color change. It appears in both reconstructive and aesthetic settings because it can affect visible areas and perceived skin uniformity.

dermatosis is a general medical term for a disorder or disease of the skin. It is often used when describing a skin finding before a specific diagnosis is confirmed. In cosmetic and plastic surgery settings, dermatosis may be discussed during pre-procedure screening or when evaluating post-procedure skin changes. It is used in both reconstructive and aesthetic care because skin health influences planning, healing, and visible results.
