Cutaneous Crohn's disease in the pediatric population

Vulvar swelling and the timely diagnosis of Crohn's disease: A case report

Children with vulvar swelling often present to multiple physicians and face a prolonged period of ambiguity and extraneous treatments. Here, we report a case of an 8-year-old girl who presented to the dermatology clinic with a 2-month history of vulvar swelling and was ultimately diagnosed with Crohn’s disease. Although extra-intestinal manifestations are common in inflammatory bowel diseases, they rarely present before an existing diagnosis. This report highlights this potential early manifestation and demonstrates how timely diagnosis leads to improved outcomes for patients, their families, and healthcare systems.

Cutaneous manifestations of metastatic Crohn's disease

Metastatic Crohn's disease is a rare cutaneous complication of primary Crohn's disease. It is a granulomatous inflammatory process, similar to the pathogenic mechanism of Crohn's disease, that occurs in sites discontiguous from the gastrointestinal tract. Metastatic Crohn's disease can precede the development of Crohn's disease by months to years, and children are more likely to present with metastatic Crohn's disease in the absence of gastrointestinal symptoms. Given that approximately 30% of individuals with Crohn's disease present in childhood, early recognition of extraintestinal manifestations of Crohn's disease such as metastatic Crohn's disease can aid in timely diagnosis and management of bowel disease. We present data from two pediatric cases of metastatic Crohn's disease recently seen at our institution in addition to the 61 reported cases of pediatric metastatic Crohn's disease in the literature. This review article will focus on the epidemiology, pathogenesis, clinical features, and histology of and treatment options for pediatric metastatic Crohn's disease.

Genital Granulomatosis in Male and Female Patients With Crohn's Disease: Clinical Presentation and Treatment Outcomes

BACKGROUND

Genital granulomatosis [GG] is a metastatic form of Crohn's disease [CD], characterised by granulomatous inflammation of the genital skin without contact with the gastrointestinal tract. Little is known about GG, as most publications are case reports or small series, and only sporadic in male cases.

METHODS AND AIMS

Cases of GG were retrospectively collected through the Collaborative Network For Exceptionally Rare case reports project of the European Crohn's and Colitis Organisation.

RESULTS

A total of 43 patients [9 males, 34 females] were diagnosed as having GG, mostly as oedema and/or ulcers. Histological confirmation of granulomas was obtained in 70% of the cases. CD location was colonic or ileocolonic in 97% and perianal disease was documented in 57%. There was no significant difference between males and females in CD phenotype or genital lesions. GG was the first manifestation of inflammatory bowel disease [IBD] in one-third of the patients; these patients were younger at the time of GG occurrence and they all were non-smokers. GG occurred in the absence of gastrointestinal disease activity in 30% of the cases. Ten out of 11 patients [91%] responded to systemic corticosteroid treatment, 5/9 patients responded to immunomodulators, and 9/11 patients responded to anti-tumour necrosis factor alpha [TNF-α] agents.

CONCLUSIONS

GG is a rare extraintestinal manifestation of CD. It mainly occurs among women, in the setting of colonic involvement of CD, and perianal disease is often associated. Most cases are successfully managed with systemic corticosteroids or anti-TNF agents.

Vulvar swelling as the first presentation of Crohn's disease in children-A report of three cases

Vulvar swelling is a rare manifestation of metastatic Crohn's disease in children. It often predates gastrointestinal symptoms and can be the first presentation of pediatric Crohn's disease. We report three cases of pediatric Crohn's disease presenting with vulvar swelling. We discuss this rare presentation and its treatment and highlight the importance of recognizing it so that prompt investigation and appropriate management can be initiated.

Vulvar involvement in pediatric Crohn's disease: a systematic review

PURPOSE

The aim of the study is to report a systematic review (from 2000 to 2017) of all pediatric cases of vulvar Crohn's disease (VCD) and to highlight the key-points for a correct diagnosis and management of this rare condition.

METHODS

An electronic search using the Pubmed/Medline, Scopus, EMBASE, Cochrane database and Google Scholar database was performed according to PRISMA guidelines.

RESULTS

Twenty pediatric studies and 22 cases of VCD were included for analysis. All the articles reported a single case, except two articles where two cases, respectively, are described. Clinical vulvar examination showed the following main manifestations: vulvar erythema (9/22 cases, 40.9%), vulvar swelling (8/22 cases, 36.4%), vulvar edema (8/22 cases, 36.4%), vulvar ulcers (4/22 cases, 18.2%). Perianal and/or anal involvement (fissures, vegetations, skin tags, erythema, papules, nodules) were recorded in ten cases (45.4%). Steroids per os and/or topical administration were the most prescribed treatment, achieving clinical remission in 11 cases (50%), used alone or in combination with metronidazole or 5-aminosalicylic acid, azathioprine or sulphasalazine/mesalazine.

CONCLUSIONS

This review shows that pediatric VCD is an uncommon disease, difficult to be diagnosed as either symptoms or clinical lesions are not specific. A multidisciplinary approach is advised to reach a correct diagnosis and plan clinical treatment.

Infantile perianal pyramidal protrusion: a case report with dermoscopy and ultrasound findings

Infantile perianal pyramidal protrusion, it is a rare benign cutaneous condition described in relatively recent times. It is considered to be under-reported in the pediatric literature because it is often mistaken for other conditions. The unawareness of this lesion may be responsible for an excessive concern both in physician and in parents, which leads to overly aggressive and unnecessary treatments. Thus its recognition has many implications regarding proper management and treatment.

We report a typical presentation of IPPP in which the diagnosis was based on the use of non-invasive diagnostic tools and in particular of dermoscopy and ultrasonography.

Crohn's disease presenting as vulvar edema in a 15-year-old girl

BACKGROUND

Vulval involvement is an uncommon extraintestinal manifestation of Crohn's disease, and it is very rare in children. Patients with vulval CD typically present with erythema and edema of the labia majora, which can progresses to extensive ulcer formation. Vulval CD can appear before or after intestinal problems or it may occur simultaneously.

OBSERVATION

We present a 15-years-old girl with bilateral labial hypertrophy which revealed a Crohn's disease. The course of her lesion was independent of the intestinal disease and responded significantly to medical treatment including Mesalamine, corticosteroid and local care.

CONCLUSIONS

We emphasize that although vulval involvement in childhood is uncommon, Crohn's disease must be considered in the differential diagnosis of nontender, red, edematous lesions of the genital area.

Sterile folliculitis as an important diagnostic clue to Crohn's disease

Sterile folliculitis is known to be one of the rare cutaneous manifestations of Crohn's disease (CD). To our knowledge it has never been emphasized as a marker of significant diagnostic value, perhaps maybe even more significant than more common cutaneous manifestations such as erythema nodosum (EN).

Crohn disease and the gynecologic patient

Although Crohn disease (CD) is considered an inflammatory bowel disease, extraintestinal gynecologic manifestations are varied, frequent, and oftentimes difficult to manage. Its predilection for young and reproductive-age women makes it an important disease process for the gynecologist to understand, as its complications can have long-term repercussions on the developmental, sexual, reproductive, and psychological health of affected women. Patients may present with a variety of vulvovaginal, perineal, perianal, and urologic complaints. Perianal involvement from an intestinal fistula is the most common skin manifestation seen in CD. Other gynecologic manifestations include metastatic CD and rectovaginal and urovaginal fistulas. Recognition and accurate diagnosis of extraintestinal gynecologic manifestations, as well as a good understanding of the gynecologic effects of chronic disease, are necessary for optimal management. The article provides an overview of CD and highlights the gynecologic considerations in caring for women affected by this disease.
