Erythema Migrans with Pustules

This 27 yo woman was sent from the E.R. with a 5 day history of a solitary 20 cm annular plaque on the right hip. It looks classical for erythema migrans (EM) of Lyme disease. Her three year-old daughter had a tick on her skin 2 weeks ago, but she has no history of tick bite. The patient is well otherwise.
Photos taken June 24, 2008


Clinically, this is Lyme disease, but no reports in literature of pustules. There is one from China with vesicles (which these may have been initially).

Lyme titers are pending (but this is a clinical dx at this point) and a culture of a pustule was taken.

E.R. doc put her on cefuroxime because she can't tolerate doxycycline (bad GI upset). She has a f/u appointment in a week.

Ranula

Abstract: 16 mo girl with mucous cyst of lower lip.
HPI: This 16 mo Chinese girl presented for evaluation of a lip lesion that has been present for two months. It waxes and wanes in size. The lesion does not appear to bother her. Her mother speaks little English and is very worried about this lesion.
O/E: 6 mm translucent cyst lower lip
Clincal Photo:

Lab/Path: N/A
Diagnosis: Mucous Cyst (Ranula)
Questions: How would you approach this patient? I need to find a translator so that I can have a meaningful discussion with the child's mother. In the past, I have treated a few of these with liquid nitrogen and they did well, but that might be very traumatic for this child (and the mother). Might have to find a pediatric ENT (the closest would be ~ 75 miles from here)

Reference: There are two good chapters on eMedicine.com
and eMedicine2.com The latter is more detailed.

This is the largest study I found, and I'll write to the authors.

CONCLUSION: Three patterns of ranula have similar clinical and histopathologic findings, although plunging ranula has some different clinical features. Removal of the sublingual gland via an intraoral approach is necessary in the management of various clinical patterns of the ranula. Recurrence rates of ranulas of any type are excessive unless the involved sublingual gland is removed.

Man from Mauritius

Presented by Dr. Philip Li Loong, Quatre Bornes, Mauritius

Abstract: 27 year old man with four year history of a papular eruption.

HPI: This man's lesions began on the face four years ago and later developed in the groins and axillae. Initially macules, they became papular and much more numerous. At onest, they were felt to be verruca plana. Cryotherapy was tried without success.

O/E: The lesions are 2 - 3 mm in diameter brown to yellowish papules. Distribution: Face, crural folds, axillae.

Clinical Photos:





Lab: Full blood count normal, cholesterol 5.2 upper limit, triglycerides normal, LDL HDL also normal, Immumoglobulins normal, plasma electrophoresis normal, thyroid function tests normal.
Pathology: Two biopsies were done.
The first showed a mild chronic inflammatory infiltrate in the upper dermis made up of small lymphocytes and histiocytes with occasional macrophages.
Repeat biopsy from the right axilla was reported as aggregates of foam cells admixed with other histiocytes, lymphocytes and some fibroblasts: "appearance consistent with eruptive xanthomas"

Diagnosis: Do you think this man has xanthoma disseminatum?

Questions: This entity may be associated with paraproteinemia and mucous membrane involvement. Comments for diagnosis and management will be most welcome. What are your thoughts? What further would you do?

Know When to Cut, Know when to Punt

The patient is an 87 yo man with a mild dementia. He lives in an assisted care facility. Has an attentive and caring daughter. In October of 2007 he had a wide-local excision of s large SCC on the left forehead by a general surgeon. Path report showed "clear margins." When seen on May 30, 2008 a 4 x 3 cm recurrence was noted. The picture of the right TMJ area shows a scar from micrographic surgery from a similar lesion the patient had ~ 10 years ago. His daughter said it took 6 months to heal.





Questions:
1. What contributes to the aggressive behavior of this small subset of SCCs?
2. Would you refer to Mohs, XRT, or just watch?
3. Are you comfortable playing God with patients like these?

Comment: There is a subset of SCCs that metastasize and kill patients. MA Weinstock and his collaborators have written on this subject.

Weinstock MA, et. al.
Nonmelanoma skin cancer mortality. A population-based study.
Arch Dermatol. 1991 Aug;127(8):1194-7.

Department of Medicine, Veterans Affairs Medical Center
Providence, RI 02908.

To estimate the magnitude of nonmelanoma skin cancer mortality
and describe itsparameters, we reviewed the medical records of
all deaths certified as due to this cause among Rhode Island
residents from 1979 through 1987. After excluding acquired
immunodeficiency syndrome-associated Kaposi's sarcoma, we
confirmed that nonmelanoma skin cancer was the cause of death
for 51 individuals, a quarter of the number of melanoma deaths
reported. The age-adjusted nonmelanoma skin cancer mortality rate
was 0.44/10(5) per year. Fifty-nine percent were due to squamous
cell carcinoma, and 20% were due to basal cell carcinoma. Most
appeared actinically induced. Among deaths from SCCs, the mean age
was 73 years. At least 80% of the squamous cell carcinomas metas-
tasized, and 47% arose on the ear. None appeared due to refusal of
treatment. Among deaths frombasal cell carcinoma, the mean age was
85 years, and refusal of surgical  intervention was documented in
40%. Study of nonmelanoma skin cancer mortality provides for estimation
of the magnitude of this problem, complements otherstudies of
prognosis, and helps guide prevention, early detection, and treatment.

Two Foot and One Hand Disease

These are the hands of a 35 year-old plumber I saw recently. He was not aware of a dermatitis of his feet, but inspection showed mild moccasin-type T. pedis on both feet and subtle onychomycosis. KOH prep from the right hand was positive for septate hyaline hyphae. We all see two foot and one hand disease regularly. Do you have any theories as to why only one hand is involved? This is a peculiar dermatologic vignette.

Penile Pain

The patient is 40 yo heterosexual male in a monogamous relationship for the last 6 years. Neither he nor his partner has a history of having had sex with anyone else ever before.

Three months ago he had the onset of pain at the tip of his glans during coitus and experienced pain also on pulling at the tip of his foreskin. A month later he noticed a few grouped "vesicles" at the ventral tip of his glans. These lesions have persisted unchanged. The pain in these lesions persists since being first noticed.
Clinical Photo:


The wife is asymptomatic although she had symptoms suggestive of vaginitis 3-4 months back which improved on clotrimazole pessaries (this was almost the same time when the patient developed pain during coitus which has never subsided).

What is the diagnosis?
What would you do at this point?

Note: Two respondents have suggested "Pearly Penile Papules." This does not look like a typical case of PPP. For comparison a picture is below. PPP is usually around the corona and is rarely this symptomatic.

21 yo man with warty plaque on foot

Presented by Henry Foong, Ipoh, Malaysia

A 21 yr old student presented with 5-year history of warty growth on the
right foot. It started as a small lesion which gradually got bigger.

Pertinent findings on examination were raised hyperkeratotic plaque 5 x 3 cm
on the medial border of the dorsum of the right foot. It has a verrucous
surface with blackish dots. Regional nodes were not palpable.




Clinically he has chromoblastomycosis of the right foot.

A biopsy was done and the epithelium shows marked acanthosis with elongation
of rete ridges and intraepithelial collections of neutrophils. The dermis is
densely infiltrated by lymphocytes, plasma cells and few neutrophils.
Culture of organism was not done.

I may repeat the biopsy and perform fungal culture.

I plan to treat him with liquid nitrogen together with some combination
therapy with antifungals: itraconazole 100mg bd ( 200mg bd??) for several
months together with another antifungals. 5FU or IV amphotericin.

Would appreciate your comments on this patient.
