Lobular capillary hemangioma (LCH-PG) is a type of pyogenic granuloma characterized by proliferating blood vessels that resemble conventional granulation tissue. Granulation tissue is very often seen in association with ingrown toenails. Despite the close relationship between both entities, LCH-PG shows clinically different behaviors, such as rapid growth and frequent recurrence. Currently, it is unknown exactly how the different etiological factors contribute to the formation of differences between entities. We present a case of a large LCH-PG associated with chronic onychocryptosis in a 26-year-old man. Histopathological features included extensive signs of ulceration, hyperkeratosis, and patchy epidermal acanthosis with the presence of fibrous septa with lobular areas beneath the ulcerative area. The presence of stroma with a marked proliferation of blood vessels with wall thickening and mixed-type inflammatory changes was also characteristic. In advanced stages of onychocryptosis, as presented here, conventional granulation tissue or pyogenic granuloma can be clinically difficult to distinguish from other benign or malignant neoplasms. Histological examination is mandatory, and excisional biopsy can provide a definitive diagnosis.

Nail matricectomy is indicated in the management of painful onychodystrophies, including recalcitrant onychocryptosis, onychogryphosis, onychauxis, and refractory onychomycosis. Although many matricectomy methods have been described, with phenolization being the best studied, no one method has clearly emerged as superior. We present a series of 14 patients who underwent a total of 18 matricectomies with either phenolization or electrodessication (ED) in a private dermatology office, and describe a simple and effective variation of the ED technique using a modified hyfrecator tip. A video demonstration of this technique is included. We also describe ED matricectomy in the context of a review of the literature, ascertaining recurrence rates, complication rates, healing time, and patient satisfaction. The nuances of technique specifics (such as the use of adjunct methods and antibiotics), as well as outcome predictors and measurements have been highlighted. We found ED to be comparable to other forms of matricectomy, with the advantages of ease of use, minimal complications, and good satisfaction rates.

BACKGROUND: Onychocryptosis, also known as ingrown toenails or ungues incarnati, is a fairly frequent condition, with global prevalence of approximately 20%.
OBJECTIVE: This study is aimed at discussing possible conservative management of severe onychocryptosis, with a case report.
METHODS: Conservative approach is effective in reducing or even entirely correcting underlying nail deformities. Eliminating nail fold inflammation is necessary prior to the bracing procedure. The non-surgical approach combined with proper wound treatment of the involved nail folds is a promising alternative for a growing number of patients.
RESULTS: Nail plate deformities may be largely corrected or fully eliminated. As demonstrated by our case report, even advanced stages of onychocryptosis may be effectively treated with nonsurgical modalities.
CONCLUSIONS: Proper podiatric care facilitates conservative approach to management of ingrown toenails, improving the patient\'s overall wellbeing and eliminating pain. The prerequisite for nonsurgical correction of the nail plate is treating inflammation first. Conservative correction is more aesthetically pleasing and less emotionally disturbing to the patients than partial or complete surgical avulsion. Lesser invasiveness is an advantage especially in the case of patients with chronic comorbidities.

Extensive hypertrophic scarring of the halluces secondary to chronic onychocryptosis is a rare condition, which causes significant physical and psychosocial effects. In this case, a 31-year-old male developed large lesions on both great toes after he delayed treatment of chronic hallucal onychocryptosis for over a decade. Current treatment options for hypertrophic and keloid lesions in the foot and ankle vary considerably and differentiation is critical for appropriate treatment planning. In this case, surgical excision with total matrixectomy (modified Zadik-Syme) was considered optimal management. Histopathology testing confirmed the diagnosis of irritated hypertrophic scar secondary to onychocryptosis. The patient was monitored closely and at 3 months post-operatively, the incisional scars exhibited progressive maturation, and there was no recurrence of the lesions and no nail regrowth. Furthermore, the halluces were only marginally shorter providing good function and cosmesis. At the long-term follow-up consultation (5.5 years), the patient indicated complete satisfaction and had returned to regular footwear and social activities. Chronic onychocryptosis can trigger and facilitate proliferation of large benign keloid-like fibrous lesions; excision with total matrixectomy can provide an excellent long-term outcome.

Onychocryptosis (ingrown toenail) is a condition commonly seen in Primary Care clinics. It is uncomfortable and restrictive for patients and has a high incidence in males between second and third decades of life. It is of unknown origin, with a number of predisposing triggering factors being involved. Treatment depends on the stage of the ingrown nail and the procedures may range from conservative to minor surgery that can be performed by the Primary Care physician in the health centre. We report the case of a 25-year onychocryptosis that did not respond to conservative management, and was extracted with partial matricectomy of the nail.
