Subungual fibromas (Concept Id: C0266003

  1. Tuberous sclerosis complex (TSC) involves abnormalities of the skin (hypomelanotic macules, confetti skin lesions, facial angiofibromas, shagreen patches, fibrous cephalic plaques, ungual fibromas); brain (subependymal nodules, cortical dysplasias, and subependymal giant cell astrocytomas [SEGAs], seizures, intellectual disability / developmental delay, psychiatric illness); kidney (angiomyolipomas, cysts, renal cell carcinomas); heart (rhabdomyomas, arrhythmias); and lungs.
  2. Subungual fibroma is a painless, slow-growing tumor seen in the nail apparatus. They can be spherical or oval in shape and firm or elastic in consistency. Fibromas may become cherry shaped or polypoid and lift the nail in the distal subungual area
  3. Subungual myxoid pleomorphic fibroma The authors report an example of pleomorphic fibroma in a unique site: the subungual space of the thumb. A 54-year-old man presented with paronychia and markedly thickened hyperkeratotic nail. The nail plate was removed, and an exophytic, red, friable, granulation tissue-like lesion was revealed sub
  4. At the 6-month follow-up, the subungual tumors were no longer noticeable, and dystrophy of the nail plate had subsided (Figure, B). Treatment was then discontinued. There were no signs of recurrence of the fibromas 6 months later, at most recent follow-up. The topical rapamycin was well tolerated without complications
  5. Subungual exostoses probably result from metaplasia in mechanical irritations or diseases of the nailbed although the precise etiology is unknown 2. The lesion is composed of mature fibrocartilaginous tissue and bone and resembles callus 1,3. [radiopaedia.org
  6. Subungual Pleomorphic Fibroma The lesion falls under the general rubric of a CD34 positive subungual fibrocytic lesion with features of a subungual fibroma. Because of the hyperchromatic stellate cells within the superficial corium it is reasonable to use the designation of pleomorphic fibroma
  7. Tuberous sclerosis is a multisystem disorder, so treatment from a team of specialist doctors is usually necessary. Skin lesions, particularly facial angiofibromas, may be psychologically distressing for some patients. Laser treatment or electrosurgery can be used to remove angiofibromas

Periungual fibroma (Koenen tumor): similar/identical histology, distinction is predominantly based on clinical findings (i.e. location, multiple lesions, patient with tuberous sclerosis); some have noted that periungual fibromas can have prominent stellate atypical myofibroblasts, may have a more prominent vascular component, and may lack the. Re: Periungal fibroma or is it nail tuft? Growing that fast it may wel be a subungual VP, highly unlikeny that it is a fibroma, shoudln't grow that quick. If it's growing at such a rate, I'd have the lady off to the GP. for a biopsy asa Subungual exostosis is an outgrowth of bone from the tip of the toe or finger. This happens below the nail hence the term subungual. It is a benign tumour derived from the bone and cartilage. Dupuytren first described the condition in 1817

Plantar fibroma is the name given to a benign lump underneath the skin on the sole of the foot. Benign means that the lump is not cancerous. A plantar fibroma is not harmful, however, it can be painful when pressure is applied, making walking and standing uncomfortable Background: Pleomorphic fibroma is a benign fibroblastic tumor characterized by pleomorphic, hyperchromatic cells or giant multinucleated cells embedded in a collagenous stroma. These cytologic features may lead to an incorrect diagnosis of malignancy. Most cases reported in the literature are located on trunk or extremities; the presentation as a subungual mass is rare In contrast to cellular digital fibroma, a subungual tumor with marked myxoid stroma that stains strongly positive with CD34 is a superficial acral fibromyxoma and a lateral digit tumor with fibroblasts oriented perpendicular to the overlying epidermis and staining sparsely (or not staining) with CD34 is an acquired digital fibrokeratoma

Periungual fibromas were seen in the feet. These lesions, usually seen in adults, are typical of tuberous sclerosis, which this patient had. In adolescents, facial angiofibromas are often mistaken. Subungual exostosis is an uncommon osteocartilagenous bone tumour that affects the distal phalanx of the toes or fingers, most commonly the hallux. The exostoses are sometimes referred to as a Turret exostoses. The condition is thought to include a true exostosis, characterised by a fibro-cartilaginous cap, and an osteochondroma, with a hyaline.

Symptoms. Dermatofibromas usually develop slowly. These small, hard, raised skin growths: Usually appear on the lower legs, but may appear on the arms or trunk. May be red, pink, purplish, gray or brown and may change color over time. May be as small as a BB pellet but rarely grow larger than a fingernail. Are often painless but may be tender. Glomus body is a special type of arteriovenous anastomosis in the dermis for thermoregulation. Glomus bodies are highly concentrated in digits, palms, and soles; thus, reflecting the predominant distribution of glomus tumor in these areas. Up to 75% of glomus tumors occur in hand; up to 65% occur at fingertips, predominantly at subungual space consider subungual exostosis a variant of osteochondroma or even fibromas, keratoacanthomas, squamous cell carcinomas, subungual malignant melanomas as well as bacterial or mycotic infections.8,12 Subungual osteochondroma's US findings have been briefl Ungual fibromas or subungual fibromas are smooth, firm growths that grow around or from underneath the fingernails or toenails.

How can Pleomorphic Fibroma be Prevented? Currently there are no mechanisms to prevent Pleomorphic Fibroma occurrence. Prompt treatment and early tumor recognition will help in having an optimal outcome. What is the Prognosis of Pleomorphic Fibroma? (Outcomes/Resolutions) Pleomorphic Fibroma is considered to be a benign condition Onychomatricoma is a rare benign neoplasm of the nail matrix that actively produces a nail plate. It should be included in the differential diagnosis of a thickened discolored nail plate with transverse overcurvature. The author presents a rare case of onychomatricoma following trauma The osteochondromyxoma, subungual exostosis, bizarre parosteal osteochondromatous proliferation and synovial chondromatosis were added to the benign chondrogenic tumours of bone. Chondromyxoid fibroma and atypical cartilaginous tumour / chondrosarcoma grade I are grouped together as intermediate (locally aggressive) tumours Subungual osteochondromas occurs mainly in adolescents and young adults. Although there are some discordant works, most authors found an equivalence between the sexes [2,3]. The most common topography of involvement is the distal phalanx of the hallux, however it can occur on any finger or toe [4-6]

The lesion may ulcerate, become painful, give rise to ingrown nail or mimic subungual wart. There is associated nail dystrophy and onycholysis. A pedunculated exophytic lesion arising from the phalanx is seen on radiographs of affected part. Treatment is surgical excision. Infantile Digital Fibromatosis/Reye's Tumo When they occur subungually, osteochondromas can easily be misdiagnosed as verruca vulgaris, subungual fibroma (garlic glove tumor), lipoma, pyogenic granuloma, or subungual digital mucous cyst. 1, 2, 5 Our patients' lesions had durations of 3 and 6 months.

Subungual lesions are uncommon and usually result in onycholysis. Multiple periungual fibromas (Koenen tumors) can occur i A subungual exostosis is a rare and benign bony overgrowth that is permanently attached to the tip of the toe 39). It was first described by Dupuytren, who observed subungual exostosis on toes; Hutchinson later reported subungual exostosis on fingertips 40). The pathology of subungual exostosis differs from that of osteocartilaginous exostoses

Fibromas resemble collagenous nevi or skin tags. Fibromas occur in all breeds but are primarily a tumor of aged dogs. Subungual squamous cell carcinomas are tumors that originate under a nail (claw). They are most commonly found in Giant and Standard Schnauzers, Gordon Setters, Briards, Kerry Blue Terriers, Scottish Terriers, and Standard. Nail lesions can be called subungual fibromas when they arise from beneath the nail and periungual fibromas when they arise from around the nail. They do not normally affect children with TSC but often start to grow later in life. They eventually affect most adults with TSC and they can range in size from being barely detectable to almost 1.
